ATQ,
Let x be the number of days taken by both Chinu and Diksha working together. Chinu takes 20 days more than both working together = C= x+20. Diksha takes 6 days more than both working together = D=x+6. The combined work rate equation is
Solve for x
Cross-multiply and simplify to get x2 = 120, so x ≈ 11. Chinu takes C = x+20 = 11+20 = 31 days.
(74.93% of 640.11 + 3/4 of 359.79)² - (1/3 of 80.87 × 2)² = ?
(800.08% of 20 - 82.16 x 2.94) = ?
150.04% of 800.08 + 20.04% of 749.89 = ? + 322.02

657.94 + 335.21 - 211.09 - 82.30 = ?
(115.25 + 324.78) ÷ 4.99 = ?2 – 56.44
245.67 + 20.05² + ?³ = √961.89 * 34.02
157.78% of 4820 + 92.33% of 2840 = ? + 115.55% of 1980
1219.98 ÷ 30.48 × 15.12 = ? × 2.16
