5 Prem solda transistor to Sudhir at a gain of 10% and Sudhir sold it

1.	5 Prem solda transistor to Sudhir at a gain of 10% and Sudhir sold it to Hari at a gain of 15%. Prem habought it for500, what did it cost to Hari?
Answer» C.P to Prem = Rs. 500Gain = 10%S.P = C.P(100+G)/100 = 500110/100 = Rs.550 C.P to Sudhir = Rs. 550Gain = 15%S.P = C.P(100+G)/100 = 550115/100 = 632.5 C.P to Hari = Rs. 632.5

Answer»

C.P to Prem = Rs. 500Gain = 10%S.P = C.P*(100+G)/100 = 500*110/100 = Rs.550

C.P to Sudhir = Rs. 550Gain = 15%S.P = C.P*(100+G)/100 = 550*115/100 = 632.5

C.P to Hari = Rs. 632.5
