Answer 1

Answer:

Step-by-step explanation:

Numbers are in the ratio 3:4

So , consider the numbers as 3x & 4x

3x = 3 * x

4x = 4 * x = 2² * x

So, LCM = 3 * 2² * x = 12x

12x = 84

=> x = 84/12 = 7

Hence numbers are 3x = 3*7 = 21

& 4x = 4 * 7 = 28

So, greater number = 28

VERIFICATION: LCM (21, 28) = 84

& 21: 28 = 3:4
