Question 122

The ratio of two numbers is 3: 4 and their HCF is 15. Then the sum of the two numbers is:

Solution

Let the numbers be $$3x$$ and $$4x$$. Since, the numbers are co-prime, their H.C.F. = $$x$$

According to ques, => $$x=15$$

$$\therefore$$ Sum of numbers = $$3x+4x=7x$$

= $$7\times15=105$$

=> Ans - (A)
