Question

If 30% of a number A is 14 less than the number A, and 60% of another number B is 4 less than the number B, what is the sum of numbers A and B?
1. 10
2. 20
3. 30
4. 40

Answer 1

Correct Answer - Option 3 : 30

Explanation:

Here, the 1st number is A,

30% of the number A = 0.3A

According to question,

0.3A + 14 = A

0.7A = 14

A = 20

Also, the 2nd number is B,

60% of the number B = 0.6B

According to question,

0.6B + 4 = B

0.4B = 4

B = 10

Sum of numbers,

A + B = 20 + 10

A + B = 30

Hence the required sum of numbers will be 30.
