Datla Kanthi 13 years AGO

Let x be the printed cost and y be CP, in equation form the above one we get
85x-100y = 3000
80x-100y = 2400
on solving we get x = 120 and y = 72
so option 3) is the answer

let sp be x. 15%of x=3x/20
now profit = cp-sp
30=cp-3x/20 .......(1)
now 20%ofx= x/5
from this 24=cp-x/5 ......(2)
from eqn 1&2 x= 120 i.e, printed cost
