Avinash has 20% less coins of different countries than Gaurav has. Gaurav has 40% more such coins than Chetan has. By what percent the number of coins which Chetan has is less than the number of coins which Avinash has?(correct to one decimal place)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 10.7
Let's the total number of coins of Chetan = 100
The total number of coins of Gaurav = 100 × (100 + 40)/100 = 140
The total number of coins of Avinash = 140 × (100 - 20)/100 = 112
The required percentage = (112 - 100)/112 × 100 = 10.71%
