Question
Find the third proportional to 11 and
33?Solution
Third proportional = a : b :: b : c It can be written as = b2 = ac  Here, a : b : c = 11 : 33 : c => 33 × 33 = 11 × c => c = (33 × 33)/11 = 99
29.81 % of 49.91 + 14.28% of 147.09 + 179.91 = ?3
480 ÷ 10 + 18 % of 160 + ? * 9 = 60 * √36
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.)...
41.98% of 2200.031 + 15% of 3999.9 = ?
(100.01% of 44.89) ÷ 14.98 = √? - √48.98
30.33% of 440.08 + 45.09 × 5.998 – √961.09 × 3.990 – 189.99 = ?
12.05% of 1399. 93 + 24.95 × 15.05 - 319.04 = ?Â
(2879.79 ÷ 24.07) × (√624.77 + √120.88) - 35% of 1199.85 = ?
