Question

raju sold a watch to sonu at 12% gain and sonu had to sells it to manu at a loss of 5%.if manu paid rupees 5320 ,how much did raju pay for it ?

Answer 1

S.P for Sonu to Monu = rs 5320

Loss = 5%

∴C.P at which Sonu bought = 100/100-loss%*S.P = 100/95*5320 = rs 5600

Hence , S.P for Raju to Sonu = rs 5600

Gain = 12%

∴C.P = 100/100+gain%*S.P = 100/112*5600= rs 5000

Answer : Hence, Raju bought it at rs 5000.

Answer 2

Answer:

Rs. 5000

Step-by-step explanation:

C.P. of Manu = Rs. 5320

Loss = 5%

S.P. of Sonu = (100/100-Loss%)* C.P. = 100/95*5320 = Rs.5600

S.P. of Sonu= Rs. 5600

Gain= 12%

C.P. of Raju= (100/100+12)* S.P. = 100/112* 5600 = Rs. 5000

Hence, Raju paid Rs.5000.
