The number of apples, oranges and mangoes is in the ratio of 5 ∶ 7 ∶ 8 respectively. The fruit seller increased the number of fruits by 40%, 50% and 75% respectively. What will be the ratio of fruits now?

Correct option is D

Given
Old Ratio = 5 : 7 : 8
Increases: 40%, 50%, 75%

Solution
​$$New\ Apples = 5 \times 140\% = 5 \times 1.4 = 7\\New\ Oranges = 7 \times 150\% = 7 \times 1.5 = 10.5\\New\ Mangoes = 8 \times 175\% = 8 \times 1.75 = 14\\$$​​
New Ratio = 7 : 10.5 : 14
Multiply by 2 to remove decimal:
14 : 21 : 28
Divide by 7:
2 : 3 : 4

Final Answer
So the correct answer is (d)
