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.)79.97% of (? + 319.96) + 15.99 = 400.01Solution
ATQ,
79.97% of (? + 319.96) + 15.99 = 400.01
80% of (? + 320) + 16 ~ 400
0.80 X (? + 320) ~ 384
? + 320 ~ 384 ÷ 0.8
? + 320 ~ 480
? ~ 480 - 320
? ~ 160
