Problem – Solving

1. Josef purchased a lawn mower which was sold at 20% discount. He paid
Php 14,800.00 for the lawn mower. How much was the original price of the
law mower?
1. Php 18,250
2. Php 18,565
3. Php 18,500
4. 18,575

## Let X = original price of the lawn mower

20% = discount given Php 14,800.00 = net price paid
X - .20X = Php 14,800.00
.80X = Php 14,800
.80 .80
x = Php 18,500.00
P 18,500 - .20 ( P 18.500 ) = P14,800
P 18,500 – P 33,700 = P14,800
P14,800 = P14,800

Ans: 3

2. Ruth is paid P 17,000 for regular 40hr. week. Up to 40 hours, she is paid at
the regular hourly rate. For overtime of more than 40 hrs, she receives 11 ½
times as much as the regular hourly rate. How many hours did she work
during a particular week when she earned about P 24,650.00 ?
1. 48 hrs
2. 52 hrs
3. 55 hrs
4. 54 hrs

Ruth’s regular rate per hour. = P17,000 / 40 hrs = P 425.00 per hr.
Ruth’s overtime rate per hour: Regular x 1.5 = P 425.00 x 1.5 = P 637.50
Ruth’s overtime pay: P 24,650 - P 7,650
Ruth’s overtime pay per hour: P 7,650 / P 637.50 = 12 hrs
Regular work week + overtime : 40 hrs = 52 hrs.

Ans: 2

3. A stationery pad that sells for P 18.50 can be bought for for P 150 when a
dozen pads are purchased at one time. What is the savings per pad, in pesos,
when the pads are purchased by the dozen?
1. P 6.95
2. P 6.50
3. P 6.75
4. P 6.00

## P 150.00 / 12 = p 12.50 per pad

P 18.50 – P 12.50 = P 6.00

Ans: 4

4. On the day of the school concert, 500 tickets were sold. The students paid
P150 each while non-students paid P200 each. If the total of P85,000 was
collected, how many non-students attended?
1. 250
2. 230
3. 260
4. 200

## Money collected = P85,000 # of tickets sold = 500 tickets

Let X = number of students Let Y = number of non-students
X + Y = 500
150X + 200Y = P 85,000
( X + Y = 500 ) 150 check: X + 200 = 500
150X + 200Y = 85.000 X = 500 – 200

## 150X + 150 Y = 75.000 X = 300

150X - 200 Y = 85.000
- 50 Y = 10.000
Y = 200

Ans: 4

the bottom and started leaking at the rate of 6 gallons/hr. How long will it takes
the faucet to refill the emptied tank?
1. 11 hrs and 29 mins
2. 11 hrs
3. 10 hrs and 48 mins

4. 13 hrs

315b/9t – 6/1
35 T - 6T = 31
29T / 29 = 315 / 29
T = 10 hrs and 89 mins
= 10 hrs and 1 hr and 29 mins
= 11 hrs and 29 mins

total estate ?
1. P 10M
2. P 9.975M
3. P 9.5M
4. P9.9M

## P 2,850,000 / 2 = P 1,425 Joe : 3 ( P1,425,000 ) = P 4,275,000

Ray : 2 ( P1,425,000 ) = p 2,850,000
Sef : 2 ( P 1,425,000 )
Total = P 9,975,000

2. P6,250
3. P6,000
4. P6,400

## solution: 30% + 20% + 10% + 16% = 76%

P25,000 x 76 / 100 = P1,900,000 / 100 = P 19,000
P25,000 - P19,000 = 6,000

Ans: 3

3. 8:00pm
4. 8:30pm

## solution: speed = distance / time ST = D

S S
T=D/S T = 600 / 50 T = 12 hrs + 30 mins (rest time)
T = 7: 30 PM

11. Ruth bought 55 copies of Phil. History and paid a total of p3,850.00. if she
buys 3 copies more of the same book, how uch will she pay in all?
1. P4,060

2. P4,260
3. P4,160
4. P4,150

## Solution: P3,850 / 55 copies = p70.00 per copy.

P 70.00 x 3 more copies = P210.00

for sale. If the defective pens are equivalent to three percent of the production,
how many pens are being produced?
1. 5,100
2.
3. 5,000
4. 5,150

## solution: Let X = no. of pens produced

3% = percentage of defective pens in proportion to production
150 = no. of defective pens

## 3%X = 150 ; 3% X = or 150/3% or 150/.03

X = 5,000

13. Timmie owns 40% of the stock in millennium Traders, Inc. Jsef owns
15,000
shares. Bernice owns all the shares not owned by Timmie nor Josef. How
many shares does Timmie own if Bernice has 25% more shares than Timmie?
1. 45,000 shares
2. 50, 000 shares
3. 60,00 shares
4. 75,000 shares

## Solution: Timmie = 40% Millenium Traders

Bernice = owns 25% more than Timmie’s share in the Company
Josef = owns shares neither owned by Timmie’s nor Bernice
= 100% - 40% - 50% - 10%

## I f Josef owns 10% of Millennium equivalents to 15,000 shares,

then Let X = 15,000 /.10
X = 150,000 thus : Timmie owns : 40% X 150,000
= 60.000

Tina to mow the lawn by herself?
1. 1 hr and 30 mins.
2. 2 hrs and 22 mins.
3. 2 hrs
4. 2 hrs and 30 mins.

## solution: Part of work done = time actually spent working

time required to accomplish work

Let X # of hours it would take Aling Tina to mow the lawn by herself.
Mang Lorenzop = 2/3 of the work done in hrs.
Aling Tina = 1 ½ hrs to finish the rest of the work. 3/2 or ½
= 3/2X = Part of the work done by Aling Tina
= 2/3 + 3 / 3X = 1
3/2X = 1/3 / 3/2
X = 2/9 or 2.22

15. A couple wants to have only four children so spaced that the first is older
than the second by 2 years, the second older than the third by three years,
the third older than the fourth by 4 years. If their plan is realized, how old will
the eldest child be when the youngest is nine years old?
1. 18 yrs. Old
2. 9 yrs. Old
3. 16 years old
4. 17 years old
5. 18 years

Solution: Let X = age of the eldest by the time the younest is nine years. Old
2 ÷ 3 + 4 = total no. of years.
9 = total no. of age difference.

## If the youngest would be 9 years old, adding the no. of age

Difference: X + 9 years = 18 years old
Youngest = 9 years old
nd
2 to the youngest = 9 + 4 = 13
nd
2 eldest = 9 = 4 = 13
2nd = 13 + 3 = 16
Eldest = 16 + 2 = 18
