The following question based on profit & loss topic of quantitative aptitude
(a) 22
(b) 24
(c) 20
(d) 25
The correct answers to the above question in:
Answer: (b)
If the CP of 20 apples be Rs.x,
then ${x × 120}/100 = 100$
$x = {100 × 100}/120$ = Rs.$250/3$
Rs.$250/3$ = 20 apples
Rs.100 = ${20 × 3 × 100}/250$ = 24 apples
Using Rule 13,
Here, a = ?, x = 100, b = 20, y = 100, Gain% = 20%
Gain% = $({ay - bx}/{bx})$ × 100%
20% = $({a × 100 - 20 × 100}/{20 × 100}) × 100%$
400 = 100a - 2000
2400 = 100a ⇒ a = 24

Question : 1
A man purchased some eggs at 3 for Rs.5 and sold them at 5 for Rs.12. Thus he gained Rs.143 in all. The number of eggs he bought is
a) 200
b) 195
c) 210
d) 190
Answer »Answer: (b)
Let he buy 15 eggs. [LCM of 5 & 3]
CP of 15 eggs = Rs.25
SP of 15 eggs = Rs.36
Gain = 36 - 25 = Rs.11
Since, Rs.11 ≡ 15 eggs
Rs.143 ≡ $15/11$ × 143 = 195 eggs
Question : 2
A man bought oranges at the rate of 8 for Rs.34 and sold them at the rate of 12 for Rs.57. How many oranges should be sold to earn a net profit of Rs.45 ?
a) 100
b) 135
c) 90
d) 150
Answer »Answer: (c)
Let the man buys 24 (LCM of 8 and 12) oranges.
C.P. of 24 oranges = $34/8 × 24$ = Rs.102
S.P. of 24 oranges = $57/12 × 24$ = Rs.114
Gain = 114 - 102 = Rs.12
Since, Rs.12 ≡ 24 oranges
Rs.45 ≡ $24/12 × 45$ = 90 oranges
Question : 3
A person bought 50 pens for 50 each. He sold 40 of them at a loss of 5%. He wants to gain 10% on the whole. Then his gain percent on the remaining pens should be
a) 40%
b) 50%
c) 15%
d) 70%
Answer »Answer: (d)
C.P. of 50 pens = 50 × 50 = Rs.2500
For profit of 10%,
S.P. = ${2500 × 110}/100$ = Rs.2750
S.P. of 40 pens at a loss of 5%
= ${40 × 50 × 95}/{100}$ = Rs.1900
S.P. of remaining 10 pens = 2750 - 1900 = Rs.850
Gain % = ${850 - 500}/500 × 100$ = 70 %
Question : 4
A fruit vendor bought bananas at the rate of 5 for a rupee and sold them 4 for a rupee. The percent gain or loss is
a) 25% loss
b) 25% gain
c) 12$1/2$% gain
d) 12$1/2$% loss
Answer »Answer: (b)
Let the vendor buy 20 (LCM of 5 and 4) bananas.
CP of 20 bananas = Rs.4
SP of 20 bananas = Rs.5
Gain% = ${5 - 4}/4 × 100 = 25%$
Using Rule 13,
Here, a = 5, x = 1, b = 4, y = 1
His gain%= $({ay - bx}/{bx})$ × 100%
= $({5 × 1 - 4 × 1}/{4 × 1}) × 100%$
= $1/4$ × 100% = 25%
Question : 5
A man buys a certain number of oranges at 20 for Rs.60 and an equal number at 30 for Rs.60. He mixes them and sells them at 25 for Rs.60. What is gain or loss per cent ?
a) Loss of 4%
b) Neither gain nor loss
c) Gain of 4%
d) Loss of 5%
Answer »Answer: (a)
Let the man buy 60 oranges (LCM of 20 and 30) of each kind. CP of the 60 oranges of the first kind
= $60/20 × 60$ = Rs.180
CP of 60 oranges of second kind $60/30 × 60$ = Rs.120
Total CP of 120 oranges = (180 + 120) = Rs.300
Their SP = $60/25 × 120$ = Rs.288
Loss = Rs.(300 - 288) = Rs.12
∴ Loss Per cent = $12/300 × 100$ = 4%
Question : 6
By selling 12 oranges for Rs.60, a man loses 25%. The number of oranges he has to sell for Rs.100, so as to gain 25% is
a) 11
b) 12
c) 10
d) 15
Answer »Answer: (b)
C.P. of 12 oranges = $60 × 100/75$ = Rs.80
For a gain of 25%,
S.P. of 12 oranges = ${80 × 125}/100$ = Rs.100
Hence, 12 Orange has to sell,
