Question
Total population of city P and Q is 2240 and 2650
respectively. If the ratio of number of males to females in city is P and Q is 4:3 and 3:2 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 = 4/7 x 2240 = 1280 & Number of females in city Q = 2/5 x 2650 = 1060 Desired difference = 1280 – 1060 = 220
If (7a + b) : (7a - b) = 7:3, then find the value of a:b?
2(3/4) of 2880 + 54% of 7520 - ? = 302
√10201 × √3969 - (52)² = √? + (60)²
