1 Answer

Answer :

Let CP of 16 types =x

CP of 1 type= x/16

Sp of rice 20%=6x/16+6x/16*20/100=9x/20

Spof rice without profir or loss=6x/16=3x/8

Sp of rice at 10% loss= 4x/16-4x/16*10/100=9x/40

Total seling price=9x/20+3x/8+9x/40 = 42x/40

now profit%= [42x/40-x]/x *100

=5%

Last Answer : Answer – A (50/3 %) Explanation – Total S.P = 16000 Rs. and Total C.P = 16000 Rs. S.P. of Ist = Rs. 8000. Gain on it = 25% C.P of Ist = Rs. (100/125 x 8000) = Rs.6400 C.P of 2nd = Rs, (16000 – 6400) = Rs. 9600. S.P of 2nd = 8000. ∴loss on 2nd commodity = (1600/9600 x 100)% = 50/3%

Description : Dharan bought a donkey and a carriage for Rs.3000. He sold the donkey at a gain of 20% and the carriage at a loss of 10%, thereby gaining 2% on the whole. Find the cost of the donkey? 

Last Answer : Let the cost price of the donkey be Rs ‘X’  Then cost price of the carriage = Rs(3000-X)  20% of X – 10% of (3000 – X) = 2% of 3000  X/5 – (3000-X)/10 = 60  2X – 3000 + X = 600  X = 1200  Hence cost price of the donkey = Rs.1200
