# [Smart Math] Ratio Proportion Problem 45

Here’s and example of a SMART MATH problem for RATIO PROPORTION.

### Problem

In a basket of fruits, the ratio of the number of mangoes to apples was 4 : 3. Ten apples are added to the basket to make the number of mangoes equal to that of apples. How many mangoes were originally there in the basket?

1. 30
2. 45
3. 35
4. 40
5. 50

### The Usual Method

Total number of mangoes originally in the basket = 4x.

Total number of apples originally in the basket = 3x.

Total number of apples after adding 10 apples = 3x + 10

$\therefore 3x+10=4x$

$\therefore 4x-3x=10$

$\therefore x=10$

Hence, total number of mangoes originally present = 4x = 4 x 10 = 40.

(Ans: 4)

Estimated Time to arrive at the answer = 30 seconds.
