Question
49.98% of 249.99 – 12.5% of 359.98 = ?% of
124.98 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.)Solution
49.98% of 249.99 – 12.5% of 359.98 = ?% of 124.98
?% of 125 ~ 50% × 250 – (1/8) × 360
?% × 125 ~ 125 – 45
? × 1.25 ~ 80
? ~ 80/1.25
? ~ 64
