Question
Given that (4A = 5B = 7C), determine the ratio
(B:C:A).Solution
Since, 4A = 5B = 7C Therefore, (A/B) = (5/4) And, (B/C) = (7/5) Let 'B' and 'C' be 7x and 5x, respectively Therefore, 'A' = 7x X (5/4) = 8.75x Therefore, B:C:A = 7x:5x:8.75x = 28:20:35 Hence, option a.

[(120.96 × 12.09) ÷ ?] ÷ 6 = 19.96% of 55.07
620.15 + 1279.98 + ? × (4.79)2 = 149.95% of 1600.14
(8.86)² × (15.01)² ÷ √624.99 = 9?
(√360.99 + 161.14) ÷ 5 × 249.98 = ?
