Answer 1

Answer:

1 SP of article is = Rs. 17,

Loss % is = 15%

So, CP of article = SP*100 / (100 - Loss%)

Putting values we get,

- CP of article = 17 * 100 /85 = Rs.20.

Hence, Cost Price of Article was Rs.20Now,

» CP of article = Rs.20

- Gain % = 15%

- SP of article = CP * (100+ Profit%) /100.

Putting values again , now,

+ SP of article = 20 * 115 /100 = Rs.23..

Hence, he must sell the Article at Rs. 23 to gain 15%

3. if 5 is for RS 90

1 is for 90/5=18

12 is for 18*12=216

216-180=36

36/180=20/100=20%

4. LET CP OF ONE ARTICLE BEX

THEN CP OF 30 ARTICLE=30X

A/Q

CP OF 30 ARTICLE=SP OF 25 ARTICLE

30X=SP OF 25 ARTICLE

..SP OF 1 ARTICLE=30X/25

=6X/5

CP OF ONE ARTICLE = X

SP OF 1 ARTICLE=6X/5

SP>CP

PROFIT=SP-CP

= 6X/5-X

=X/5

PROFIT%=PROFIT/CP*100

=X/5*1/X*100

=20

.:PROFIT=20% ANS
