1.	On the glasses of following spectacles, write numbers such thati. Their sum is 42 and difference is 16.ii. Their sum is 37 and difference is 11.iii. Their sum is 54 and difference is 20.iv. Their sum is 57 and difference is 17
Answer» ii. x + y = 37 and x – y = 11 ∴ x = 24, y = 13 iii. x + y = 54 and x – y = 20 ∴ x = 37, y = 17 iv. x + y = 57 and x - y = 17 ∴ x = 30, y = 13

On the glasses of following spectacles, write numbers such thati. Their sum is 42 and difference is 16.ii. Their sum is 37 and difference is 11.iii. Their sum is 54 and difference is 20.iv. Their sum is 57 and difference is 17

Answer»

ii. x + y = 37 and x – y = 11

∴ x = 24, y = 13

iii. x + y = 54 and x – y = 20

∴ x = 37, y = 17

iv. x + y = 57 and x - y = 17

∴ x = 30, y = 13
