Question

Find the missing number in the following question.

• A. $32$
• B. $42$
• C. $62$
• D. $82$

Answer 1

Given that,

• $27^{2} = 729$
• $28^{2} = 784$
• $29^{2} = 841$

The value written inside the circle $ = 27+28+29=84$

Similarly,

• $13^{2} = 169$
• $14^{2} = 196$
• $15^{2} = 225$

$\therefore$ The value written inside the circle $ = 13+14+15=42.$

So, the correct answer is $(B).$
