The answer is -30.
60 and 25 = 85
25 and 33
It is 61: you do not need to estimate a sum as simple as that!
The numbers are: 37.5+20.5 = 58 and 37.5-20.5 = 17
92 and 34
The two numbers whose sum is 58 and whose difference is 16 are 21 and 37.
The sum of two numbers between 20-40 is 58. The difference is 12
65 + 58 = 123 65 - 58 = 7 The two numbers are therefore 58 and 65.
33+25=58 32+26=58 14+44=58 etc......
The sum of 37 and 58 is 95.
37 and 21
25% of 60 is 15.
