Question

Sum of the two numbers is 420 and their difference is 86, then find the two numbers​

Answer 1

Step-by-step explanation

Let the numbers be a and b

ATQ

a + b = 420 ......... (1)

a - b = 86 ...........(2)

add equation (1) and (2)

a + b = 420

a - b = 86

......................

2a = 506

a = 253

put a = 253 in equation (1) , we get

a + b = 420

or 253 + b = 420

or b = 167

hence the required number is (a = 253 and b = 167)
