Question
Rs. 156 is to be shared among 40 students, if each girl
receives Rs.4.50, and boy receive Rs.3.50. Find the ratio of number of boys and girls.Solution
ATQ, Let the number of boys be y, then number of girls will (40-y) According to question- 3.5×y + 4.5× (40-y) = 156 180 – y = 156 Y = 180-156 = 24 Hence number of boys = 24, and number of girls = 40-24 = 16 Ratio = 24:16 = 3:2
2660.03 ÷ 94.98 x 59.9 = ? + 20.32

Find the approximate value of Question mark(?). No need to find the exact value.
(519.79 ÷ 10.03) × (47.98 ÷ 6) + √(63.94) × 4.04 = ?
...447.79 ÷ √(√2400) + 30.94 × 6.07 – 5.08 × 21.96 = ?
1131.98 + ? – 1125.04 = 1364.93 – 1168.01
11.11% of 1800.89 + 34.89 X 10.99 - 500.50 = ?
(3/7 of 1049.88 + 44.95% of 799.79) ÷ (√168.89 + 24.77% of 400.11) = ?
- 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.)
If a:(b+c) =3:9 and c:(a+b) =10:14 then find the value of b:(a+c)?
