(b) Rs.80
(c) Rs. 60
(d) Rs. 50

solutions :


Ans 1. let original value = Rs. 100; then
S.P = 90/100 X 88/100 x 85/100 = Rs. 67.32
Hence , amount of single discount = 100 - 67.32 = 32.68%

Ans 2. Net S.P = 80/100 X 90/100 X 2000 = Rs. 1440

Ans 3. Let C.P . = Rs. 100; then marked price = Rs. 125
Hence, S.P. = 84/100 X 125 = Rs. 105
Since, actual profit = 105-100 = 5%

Ans 4. S.P. = 85/100 x 30 -1.50 = 25.50- 1.50 = Rs. 24
Required C.P . = 100/120 X 24 = Rs. 20

Ans 5. Let C.P = Rs.100, then marked price = Rs. 120
Since , S.P = 60 + 1/4 X 80/100 X 120 + 1/4 X 60/100 x 120
= 60 + 24 + 18 = Rs. 102
Hence, gain% = 102 - 100 = 2%

Ans 6. Marked price = 100/120 x 2880 = Rs. 2400
C.P. for kaushal = 85/100 X 2400 = Rs. 2040

Ans 7. Required C.P. = 95/100 x 100/115 x 6500 = Rs. 5369.56 = Rs. 5350.

Ans 8. Required profit % = 100-90 / 90 X 100 = 10/ 90 x 100 = 11 1/9%

Ans 9.Actual price = 96/100 x 2,00,000 + 97.5/100 x 72,000 = 1,92,000 + 70,200 = Rs. 2, 62,200

Ans 10. Let C.P of each clock = Rs.x ; then C.P of 90 clocks = Rs. 90x In Ist condition ,
S.P . of 90 clocks = 40 x 110/100 x + 50 x 120/100 X x = Rs. 104x. In IInd case,
S.P of 90 clocks = 115 /100 x 90x = Rs. 207x/2
Since, 104x - 207x/2 = Rs. 40 => x/2 = 40 ∴ x= Rs.80
