By selling 20 metres of cloth a man gains the selling price

Home » Aptitude » Profit and Loss » Question
  1. By selling 20 metres of cloth a man gains the selling price of 4 metres of cloth. The gain percent is
    1. 25
    2. 30
    3. 35
    4. 20
Correct Option: A

From question , S.P. of 20 metres of cloth = C.P of 20 metres of cloth + S.P of 4 metres of cloth
⇒ S.P of (20 – 4 = 16 ) metres of cloth = C.P of 20 metres of cloth
Let C.P of 1 metre of cloth = $ 1
∴ C.P of 16 metres of cloth = $ 16
S.P of 16 metres of cloth = $ 20
Gain = S.P of 16 metres of cloth - C.P of 16 metres of cloth = 20 - 16 = $ 4
∴ Gain % =
Gain
× 100
C.P of 16 metres of cloth

Gain % =
100
= 25%
4

We can find gain % with the help of given formula :
Here, p = 20, q = 4,
Gain % =
y × 100
p - q

Gain % =
4 × 100
20 - 4

Gain % =
4
× 100 = 25%
16
