Question 2

Calculate the value of $$\frac{59881\times59881-49681\times49681}{10200}$$

Solution

Expression = $$\frac{59881\times59881-49681\times49681}{10200}$$

= $$\frac{(59881)^2-(49681)^2}{10200}$$

Using, $$a^2-b^2=(a-b)(a+b)$$

= $$\frac{(59881-49681)\times(59881+49681)}{10200}$$

= $$\frac{10200\times109562}{10200}=109562$$

=> Ans - (B)
