Question 40

If 70$7 = 10, 50$5 = 10 and 40$8 = 5, then find the value of 10$2 = ?

Solution

Given : 70$7 = 10, 50$5 = 10 and 40$8 = 5

If we replace '$' with $$'\div'$$, then we will get the desired result.

Eg :- $$\frac{70}{7}=10$$

and $$\frac{50}{5}=10$$

and $$\frac{40}{8}=5$$

Similarly, $$\frac{10}{2}=5$$
