Question

4. Convert the following into m. b) 7 km 650 m a) 8 km d) 72 km 6 m c) 54 km 150 m​

Answer 1

Step-by-step explanation:

Given that, S.P.=Rs.6750 and Discount=10%

We know that,

S.P.=M.P.[1−

100

Percentage discount

]

∴ M.P.=Rs.(

90

6750×100

)=Rs.7500

Also given that, if there was no discount, S.P.=Rs.7500 and Profit=50%

We also know that,

C.P.=[

100+Profit %

100×S.P.

]

∴ C.P.=Rs.(

150

7500×100

)=Rs.5000

∴ Actual profit=Rs.6750−Rs.5000=Rs.1750

And actual profit%=

5000

1750

×100=35%

Hence, option D is correctq
