Answer 1

Step-by-step explanation:

11. He lost 5% on it therefore he bought it at

Rs.( x × 95/100 = 11400.

= Rs.(x = 12000)

= Rs.12000

12. The C.P. of the calculator was Rs.( x × 106/100 = 1325)

= Rs.( x = 1250) = Rs.1250.

Therefore, he should have sold it to gain 12% for

Rs.(1250×112/100)= Rs.1400.

13. The C.P. of the computer was

Rs. ( 24480×96/100)=Rs.23500.8

Therefore, he should have sold it to gain 46% for

Rs. ( 23500.8× 146/100) = 34311.168

14. 20%-15% =5%

5% = Rs.108

1% = Rs.108/5

100% = Rs. 108/5×100= Rs.2160.

Therefore, the C.P of the tricycle was Rs.2160.

15.

14% = Rs.3360

1% = Rs.240

100% = Rs.24000

Therefore, Sandeep bought the television at Rs.24000.
