Question : 22 [SSC CPO S.I.2008]
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 : 23 [SSC CPO S.I.2009]
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 : 24 [SSC CGL Tier-1 2011]
A man sold 20 apples for Rs.100 and gained 20%. How many apples did he buy for Rs.100?
a) 22
b) 24
c) 20
d) 25
Answer »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 : 25 [SSC CGL Tier-1 2011]
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
