### Question 1

What is the LCM of 27, 102 and 135?

### Question 2

What is the HCF of 36, 48 and 27?

### Question 3

The sum of LCM and HCF of two numbers is 188 and LCM is 93 times the HCF. If one of the two numbers is 186, then the other number is?

**A**

2.

**B**

4.

**C**

3.

**D**

5.

**Soln.**

**Ans: a**

Let L be the LCM, and H the HCF. Then H + L = 188, and L = 93H. Solving these for H, we get H = $188/{93 + 1}$ = 2, and L = 186. The product of the two numbers is equal to the product of the lcm and hcf = 2 × 186 = 372. The other number is 372/186 = 2.

### Question 4

Two numbers are in the ratio 4 : 1. If their HCF and LCM are 12 and 48, which of these is the smaller number?
