Question

5+3=16, 7+3=40, then 9+3=.......????

Answer 1

The answer is 72.

As, (5+3)×2=8×2=16

(7+3)×4=10×4=40

Similarly, (9+3)×6=12×6=72

Answer 2

Given,

5+3 = 16

7+3 = 40

To find,

The value of (9+3).

Solution,

The value of (9+3) will be 72.

We can easily solve this problem by following the given steps.

Now, if we carefully observe the given values, we observe that there is a pattern that is being followed.

According to the question,

5+3 = 16

7+3 = 40

The results are obtained by following the given pattern,

(5+3) × 2 = 16

(5+3) × 2 = 16(7+3) × 4 = 40

Or in simple words, the two given numbers are to be added and the result is to be multiplied by the consecutive multiple of 2.

So, to find the value of (9+3), we have to multiply the addition by the third multiple of 2 (6).

(9+3) × 6 = 12×6

72

Hence, the value of (9+3) is 72.
