Answer 1

Step-by-step explanation:

12) Loss

11) 75%

let price 100%

atq,

first discount 100×50/100=50

and

second discount 50×50/100=25

total discount=50+25=75%

10) option [B]

9) profit or loss percent are always

calculated on COST PRICE only.

8) option B

gain = selling price - cost price

7) option C

6) option:-B

let fruits are 100%

first he sells 30% fruits

i,e 100×30/100=30%

remaining 100-30=70%

from 70% fruits vendor throws away 40%

i,e 70×40/100=28%

remaining 70-28=42%

next day he sells 50% of his fruits

42×50/100=21%

remaining 42-21=21%

[remaining 21% fruits thrown by him]

hence total fruits thrown by him is

first day+second day

28+21=49%

5) option:-C

let price of commodity 100

atq

100×110/100×120/100×80/100

=11×12×8/10

=1056/10=105.6

net increase

105.6-100=5.6%

4) let income of B is 100x%

then A income is 60x%

atq

A savings 10x% and B savings 20x%

then

A expenditure is 54x%

B expenditure is 80x%

now according to question

A expenditure is 260 less than B

i,e

80x-54x=260

26x=260

x=10

therefore

income of A is 60x=60×10=600

and

B=100x=100×10=1000
