AFCAT Model Paper 8

Calculation:
Let the cost of the cloths be Rs. 1 per m.
On selling 1 m cloth,
CP = Rs. 100
Profit of the shopkeeper = 10%
⇒ SP of 1 m cloth = Rs. 110
But his overall profit is 30%
Let the shopkeeper uses x cm in place of 1 m
Then, CP of the cloth = Rs.x
But, he sells the cloth in Rs. 110
⇒ Profit = (110 – x)
⇒ Profit % =(110–x)×

100

x

=30%
⇒

(110–x)

x

=

3

10

⇒ 1100 – 10x = 3x
⇒ 13x = 1100
x=

1100

13

∴ The shopkeeper uses

1100

13

cm instead of 1m.
