Explanation Formula used: All percent problems can be solved by using the formula P B = R 100 . Where B is the base or whole or total amount, a standard used for comparison, P is the percentage or part being compared with the base and R is the rate or percent, a percent number. Calculation: Here P = 1.4 , R = 25 By using the percent problem formula find the value of B as follows
