Answers with explanation
1. (b): C.P.=Rs. 100. Then, marked price=Rs. 130.
Therefore, S.P.=93(3/4)% of Rs. 130=(375/400)X130=121(7/8).
Hence, gain=21(7/8)%.
2. (b); S.P. after 20% discount=80% of Rs. 750=Rs.600
Net S.P. desired=Rs. 540.
Additional discount=[(60/600)X100]%=10%
3. (c): Let C.P.=Rs. 100. Then, marked price=Rs. 110.
S.P=90% of Rs. 110=Rs. 99. So, loss=1%
4. (b); Let C.P.=Rs. 100. First S.P.=Rs. 120
Now, S.P. =Rs. 120, commission=10%
Therefore, Marked Price=[(100/90)X120]=Rs. 400/3.
No, marked price=400/3, commission=15%
Therefore, S.P.=85% of 400/3=[(85/100)X(400/3)]=340/3.
Therefore, Gain%=[(340/3)-100]=40/3=13(1/3)%.
5. (b); Let the labeled price be Rs. 100.
S.P. in 1st case=Rs. 80, S.P. in 2nd case=Rs. 75.
5 : 100 : : 500 : x.
So, x=[(100X500)/5]=10000.
6. (b); Let original price=Rs. 100.
Final price=90% of (80% of 60% of 100)
=[(90/100)X(80/100)X(60/100)X100]=43.20.
Therefore, Single discount=(100-43.20)%=56.8%
7. (d); S.P. of 40% discount=60% of Rs. 500=Rs. 300
S.P. after two successive discounts of 36% and 4%
=96% of (64% of 500)=[(96/100)X(64/100)X500]=Rs. 307.20.
Therefore, Required difference=Rs. 7.20.
8. (b);(90% of 80% of 80% of Rs. 20000)=Rs. 11520.
(95% of 95% of 60% of Rs. 20000)=Rs. 10830.
Therefore, Saving=Rs. (11520-10830)=Rs. 690.
9. (c); Net price after two discounts=80% of 90% of Rs. 10000=Rs. 7200.
Net C.P.=(7200+10% of Rs. 7200)=7920.
Therefore, S.P. =110% of Rs. 7920=Rs. 8712.
10. (d); Let the marked price be Rs. x.
95% of x-93% of x=15
2% of x=15
x=(15X100)/2=750
