Question
A sum of Rs. 178 needs to be divided among 60 students
in a class, where each boy receives Rs. 2.5 and each girl receives Rs. 3.5. Determine the ratio of boys to girls in the class.Solution
Let number of boys is x Number of girls in the class = 60 – x According to question; 2.5x + 3.5 × (60 – x) = 178 2.5x + 210 – 3.5x = 178 Or, x = 32 Desired Ratio = 32:(60 – 32) = 32:28 = 8:7 Hence, option b.
{(23.65 × 35.12) ÷ 6.97} + 179.86 = ? × 14.76
Find the approximate value of Question mark(?). No need to find the exact value.
(34.95 × 7.03) ÷ 5 + 27.98% of 249.88 – √(80.81) = ?
...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.)...
9.89 x 4.99 + 2.01 x 49.89 = ?% of 299.69
What approximate value will replace the question mark (?) in the following?
29.99...
What will be the approximate value of the following questions.
(74.75% of 600.29 – 44.85% of 399.99) × (√224.95 ÷ 15.01) = ?
( 1000)1/3 × 10.11 × 4.97 ÷ 10.32 =? – 15.022
12.03 x 4.21 +19.95% of 300.05 = ?
79.79% of 299.87 - 54.67% of (39.982 - 9.822 ) = ? - 19.92 × 199.98
