Question

of two number the smaller one is 2/3 part of the bigger one their sum is 120. what is the number​

Answer 1

Answer:

Answer = 72 and 48 Solution- Say the two numbers are x and y. x is smaller and y bigger x=2y/3 ..equation 1 and, x+y=120 ..equation 2 Putting equation 1 in equation 2 2y/3+y=120 (2+3)y/3=120 5y=120×3=360 y=360/5=72 So x =120-72 or 72/3×2= 48 So the two numbers are 72 and 48.

Answer 2

Step-by-step explanation:

Let, the bigger number is X.

So, the smaller number will be 2X/3.

Acc. to question,

X + 2X/3 = 120

or, 5X/3 = 120

or, 5X = 120 × 3 = 360

or, X = 360/5 = 72

◆The bigger number is = 72

◆Smaller number = 72× 2/3 = 48
