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.) 21.42 × 12.98 + 9.63 × 7.89 – 145.39 = ?Solution
ATQ,
21.42 × 12.98 + 9.63 × 7.89 – 145.39 = ?
≈ 21 × 13 + 10 × 8 – 145
= 273 + 80 – 145
= 353 – 145
= 208
More Approximation Questions
12.5% of (100 + ?) = 40
2/9 of 5/8 of 3/25 of ? = 40
24 × √? + 4008 ÷ 24 = 40% of 200 + 327
7(1/2) – 3(5/6) = ? − 2(7/12)
280 ÷ 14 + 11 × 12 – 15 × 6 = ?
1550 ÷ 62 + 54.6 x 36 = (? x 10) + (28.5 x 40)
25% of 1000 + 10% of 150 – 22 × ? = 45
√ 729 × 5 – 220 % of 15 + ? = 120% of 160
What will come in the place of question mark (?) in the given expression?
(40% of ? × 43 ) – 232 = 751
180 % of 45 + √144 × 8 = ?2 + 80 % of 70
