The sum of three numbers a, b and c is 60. If we decrease a by 7, we get the value N. If we increase b by 7, we get the value N. If we divide c by 7, we also get the value N. What is the value of N?

a + b + c==60,  a - 7==b +7,  b + 7==c/7, solve for a, b, c

 

a ==41/3,   b== - 1/3,   c==140 / 3

 

N ==41/3 - 7 ==20/3............(a)

N == - 1/3 + 7==20 /3.........(b)

N==[140/3] /7==20/3.........(c)
