Question : A man buys 21 mangoes for a rupee. How many mangoes had he sold for a rupee so that there is a loss of 30%?
Option 1: 30
Option 2: 40
Option 3: 35
Option 4: 25
Correct Answer: 30
Solution :
A man buys 21 mangoes for a rupee.
1 rupee = 100 paise
For a loss of 30%, he sells 21 mangoes in 100 – 30 = 70 paise
So, in 100 paise, the number of mangoes he sells $=\frac{21}{70}×100=30$
Hence, the correct answer is 30.
