Determine the mean proportion of 40 and 19.6
The ratio between two numbers is 7:8. If each number is increased by 9, the ratio between then become 10:11, find the difference between numbers.
Given that (4A = 5B = 7C), determine the ratio (B:C:A).
Some amount was divided among A, B and C in the ratio 4:5:8. If the share of A is 32 less than share of C, then find the 1/4th of total amount (in Rs).
If A : B = 7:5 and A is 14 more than B then find the sum of A and B.
