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.)341.98 + 228.09 - ? X 7.01 = 20.01 X √120Solution
ATQ,
341.98 + 228.09 - ? X 7.01 = 20.01 X √120
342 + 228 - ? X 7 ~ 20 X √121
570 - ? X 7 ~ 20 X 11
570 - ? X 7 ~ 220
? X 7 ~ 570 - 220
? ~ (350/7)
? ~ 50
