let the no. be X and Y
A/Q
X + Y = 70. 1
X - Y = 32. 2
on adding 1 and 2 we get
2X = 102
X = 102÷ 2
X = 51
putting the value of X in equation 1 we get
X + Y = 70
51 + Y = 70
Y = 70 - 51
Y = 19
A/Q
X + Y = 70. 1
X - Y = 32. 2
on adding 1 and 2 we get
2X = 102
X = 102÷ 2
X = 51
putting the value of X in equation 1 we get
X + Y = 70
51 + Y = 70
Y = 70 - 51
Y = 19
