Question

64. The surn of two numbers is 4312.
If one of the numbers is three
times the other, what is the greater
number?​

Answer 1

Let the two numbers be x and y

x+y = 4312, or

y = 4312 - x …(1)

y = 3x …(2)

Equate (1) and (2)

4312 - x = 3x, or

4x = 4312

so x = 4312/4 = 1078

So the smaller number is 1078 and the larger one 3234.
