Madhya Pradesh Police Exam Model Paper 10

GIVEN:
A man purchases some mangoes at the rate of 24 mangoes for Rs. 1.
CONCEPT:
Basic concept of Profit and Loss.
FORMULA USED:
SP = CP × [1 + Profit]/100
CALCULATION:
Given, CP of 24 mangoes is Rs. 1.
⇒ CP per mango = Rs 1/24
Also,
Profit = 20 % of CP = 1/5 CP
So,
SP = CP + Profit = 6/5 CP.
⇒ SP per mango = Rs 6/5 × 1/24 = 1/20
Since, SP of 1 mango = Rs 1/20
⇒ No. of Mangoes sold for Rs. 1 = 20
