Question
What approximate value will come in place of the question
mark (?) in the following question? (Note: You are not expected to calculate the exact value.) (45.02²- 14.99²) ÷ 8.99 = ? X 25.02Solution
ATQ,
(45.02²- 14.99²) ÷ 8.99 = ? X 25.02
(45²- 15²) ÷ 9 ~ ? X 25
1800 ÷ 9 ~ ? X 25
200 ~ ? X 25
? ~ (200/25)
? ~ 8
