Question

multiple of 9 between 43 and 100​

Answer 1

Case-1: 2+2 which is equal to 4.

Case-2: 2+2+2 which is equal to 6.

In the first case, adding two “2”s implies multiplying “2” for 2 times. So, 2*2=4.

In the second case, adding three “2”s implies multiplying “2” for 3 times. So, 2*3=6.

Now, coming to the multiplication table of 4,

4*1 = 4 ——Adding “4” for 1 time

4*2 = 8 ——Adding “4” for 2 times

4*3 = 12 ——Adding “4” for 3 times

4*4 = 16 ——Adding “4” for 4 times

4*5 = 20 ——Adding “4” for 5 times

4*6 = 24 ——Adding “4” for 6 times

4*7 = 28 ——Adding “4” for 7 times

4*8 = 32 ——Adding “4” for 8 times

4*9 = 36 ——Adding “4” for 9 times

4*10 = 40 ——Adding “4” for 10 times

Here, 4,8,12,16,20,24,28,32,36,40 are the multiples of 4.

Between 10 and 40, (12, 16, 20, 24, 28, 32, 36) are the multiples of 4.
