Let the c.p. of the calculator be 'x'
s.p of the 1st calculator = 66
A/q
x+10/100x = 66
11x/6=66
x=60
So ,cp =60 rupees
Total c.p = 60×2=120
Total s.p.= 120+15℅ of 120
=120+15/100×120
=120+18
=138
S.P-C.P.
=138-120
=18
So second calculator should be sold at a profit of (18-6)
=12
So S.P. =120+12
=132
