If a exceeds b by x%, then which one of the following equations is correct ?

The population of a village is 5000 and it increases at the rate of 2% every year. After 2 years, the population will be…

If 80% of A = 50% of B and B = x% of A, then the value of x is :

If A is equal to 20% of B and B is equal to 25% of C. Then what percentage of C equal to A ?

A number reduced by 25% becomes 225. What percent should it be increase so that it becomes 390 ?

Solve this : 36% of 365 + (?)% of 56.2 = 156.69

Solve this :<br> (0.85% of 405) + (2.25% of 550) = ?

Out of two numbers, 40% of the greater number is equal to 60% of the smaller. If the sum of the numbers is 150, then the…
