Question

What should be added in sum of 24.57 and 36.3 to get 70

Answer 1

Let x should be added,

(24.57) + (36.3) + x = 70 

24.57 + 36.3 + x = 70 

60.6 + x =70 

x = 70 - 60.6 

x = 9.4 



Hence,9.4 should be added.

Answer 2

Let the number be x. Then,
A. T. Q.
(24.57+36.3)+x=70
60.87+x=70
X=70-60.87
X=9.13
Therefore, the number is 9.13
