Question
A sum of ₹4,360 was to be divided among A, B, C, and D
in the ratio 3:4:5:8, but it was divided in the ratio 1/3:1/4:1/5:1/8. Was divided by mistake: which of the following statements will hold as a result.Solution
ATQ, The sum was to be divided in the ratio 3:4:5:8. Let the sum of A, B, C, and D is 3x,4x,5x, and 8x respectively. According to the question, we get 20x = 8720 x=436 so, we get A = 1308; B = 1744; C = 2180; D =3488 But by mistake it was divided in the ratio; 1/3: 1/4: 1/5: 1/8 By Equating, the ratio will be 40: 34: 24: 15. The new sum of A, B, C and D will be 40x, 30x, 24x and 15x respectively. Solving in the same way, we get A =3200, B = 2400, C = 1920 and D = 1200 So, we can say D got 2288 less.
15.99% of 549.99 ÷ 11.17 = ? ÷ 20.15
74.91% of 639.95 – 599.98% of 45 + 119.987 = ?
(4.88 × 5.76)2 - ?2 = 39.89 × 19.86

(1800.23 ÷ 29.98) + (816.32 ÷ 23.9) + 1634.11 = ?
1449.98 ÷ 50.48 × 10.12 = ? × 2.16
36.05 × 5.02 + 12.052 = ? + 9.09 × 4.04
(31.9)3 + (34.021)² - (16.11)3 - (42.98)² = ?
