To find:

Find the answer without doing multiplication twice​

Solution:

From the data,

Ayushman's answer = 23,54,167 × 34

Actual answer = 23,54,167 × 43

By the distributive property of multiplication

Ayushman's answer is 2354167 × 34

= 2354167 × (30 + 4)

= 2354167 × 30 + 2354167 × 4

= 80041678

Actual answer = 2354167 × 43

= 2354167 (40 + 3)  

= 2354167 × 40 + 2354167 × 3

= 101229181

Difference = Actual answer - Ayushman's answer

= 101229181 - 80041678

= 21187503

Therefore,

The difference is 21187503
