​

Answer 1

Answer:

7.gain, GAIN % is 8.64%

8.11.1%of loss%

9.Profit , profit%=20%

Step-by-step explanation:

7. C.P = Rs 3240

S.P = 43 × 80

=. 3520

Gain = S.P - C.P

= 3520-3240

= ₹280

Gain % = gain × 100 / C.P

= 280 × 100 / 3240

= 8.64 %

8. S.P = 0.80 Rs.

S.P. of 100 bananas

= 0.80 × 100

= 80 Rs.

Step-2  C.P>S.P. Therefore it is loss.

Loss   = C.P - S.P.

         = 10 Rs

Loss % = Loss /C.P  × 100

            = 10/90 × 100

            = 11.1%

9. C.P of typewriter = 1,200 Rs

Money spent on repairs= 200

Total money used for typewriter = 1400

C.P<S.P

Therefore it is gain.

Profit = S.P-C.P= 1,680-1,400= Rs.280

Profit%=Profit/C.P × 100

            = 280/1400× 100

            = 20%
