Question
A 480 ml mixture has milk and
honey in the ratio 7:h. After adding 96 ml of milk and 24 ml of honey to this mixture, the ratio of milk to honey in the resulting mixture becomes 8:7. Determine the value of h.Solution
ATQ, Let, quantity of milk in 480 ml of mixture be ‘a’ ml So, quantity of honey in 480 ml of mixture = ‘480 – a’ ml According to question; (a + 96)/(480 – a + 24) = 8/7 Or, 7a + 672 = 4032 – 8a Or, 15a = 3360 Or, a = 224 Quantity of milk in the mixture (initially = 224 ml Quantity of honey in the mixture (initially) = 480 – 224 = 256 ml Ratio of milk to honey in the mixture (initially) = 224:256 = 7:8 So, h = 8

- 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.)
2 (1/4)% of 7999.58 + {49.06% of 898.87} + √143.14 – 19.99% of 1499.63 - (52 - 41) = ?
√1024.21 × √624.89 ÷ 4.98 + 11.99 × 4.01 = ?
?% of 1200.22 + 319.82 = 3.99 × 295.64
? 2 + (39.99 × 10.99 + 7.01) - (39.99 × 2.99 2 + 21.99) = 21.99 × 23.01
510.11 ÷ 16.98 × 5.14 – 119.9 = √?Â
Solve the given equation for ?. Find the approximate value.
(35.86 × 15.14) ÷ 9 + √(288.89) × 4.03 = ?
...24.75% of 20.125% of 30.05% of 2196.06 = ?Â
? + 163.99 – 103.01 = 24.01 × 6.98
