Question
A vessel holds (p + 200) liters
of milk and p liters of honey. When 110 liters of honey and 50 liters of milk are added to the vessel, the ratio of milk to honey in the mixture becomes 5:3. What % of the initial mixture does the initial quantity of honey represent?Solution
ATQ, (p + 200 + 50)/(p + 110) = 5/3 (p + 250) × 3 = (p + 110) × 5 3p + 750 = 5p + 550 2p = 200 p = 100 Initial quantity of honey = 100 liters Initial quantity of mixture = 100 + 200 + 100 = 400 liters Required % = (100/400) × 100 = 25%
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
- 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.)

(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 × 4.04Â
(31.9)3 + (34.021)² - (16.11)3 - (42.98)² = ?
