ATQ, Formula used: SI = (P × R × T)/100 where I = Interest, P = Principal, R = Rate and T = Time Explanation: Let principal = x then, Interest = x × 6/5 = 6x/5 6x/5 = (x × 20 × T)/100 ⇒ 6x/5 = (x × T)/5 ⇒ T = 6 years ∴ The time will be 6 years.

(74.93% of 640.11 + 3/4 of 359.79)² - (1/3 of 80.87 × 2)² = ?
[(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 = ?
420.11 ÷ 13.98 × 5.14 – 124.9 = √?Â
