    Step-by-step explanation:

    15% profit means if C.P is Rs 100, profit is Rs 15

    therefore SP = 100 + 15 = Rs 115

    now when SP is Rs 345

    CP = 100 / 115× 345= Rs 300

    therefore CP = Rs 300

    now profit = profit percent /cp×100

    = 25/300×100

    = Rs 8.3

    SP = Cp + profit

    = 300+8.3

    SP =RS 308.3

    therefore cp = rs 300

    sp = rs 308.3
