Question
Total population of city P and Q is 3410 and 4620
respectively. If the ratio of number of males to females in city is P and Q is 7:4 and 4:3 respectively, then find the difference between number of males in city P and number of females in city Q.Solution
Number of males in city P = 7/11 x 3410 = 2170 & Number of females in city Q = 3/7 x 4620 = 1980 Desired difference = 2170 – 1980 = 190
5.25 x 4.09 + 3.99 x 9.67 + 6.01 x 14.88 = ?
189.23 + 18.11² + ?³ = √841.76 * 28.94
[(√2024.85 ÷ 3.01) + (35.76 ÷ 11.92)]² × (3/4 of 39.99) = ?
What approximate value should come in the place of question mark (?) in the following questions?
(1785.99 / 2.98) + (2449.89 / 6.99) - 49.99 x 4.01 = ?
?% of (144.31 ÷ 17.97 × 60.011) = 239.98
What approximate value should replace the question mark?
(839.90 ÷ 21.00) + (219.96 ÷ 11.00) = ?% of 400.0 - 40.4
- 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.)
194.95 + 3.98 × 64.99 - ? = (10.99 + 9.02)2
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.)<...
9.992 + (5.01 × 4.98) + ? = 225.03
