Question

sohan the toy shop owner sold two tricycles at the same price.each one was sold for 2200 on one he made a profit of 10 percentage .and on the other he lost 12 percentage what was the cost of each of the cycle ?

Answer 1

SP of each tricycle = 2200

tricycle 1
SP = 2200
P%= 10%

now, we will use the 7 by 7 method
take 100 as the CP, and for every 10% P, it is an increase of 10 rupees

                CP                         SP
                100                       110
                   ?                        2200
So how do we solve this?
2200 * 100 
       110
= 2000 rs
This was the cost of the first tricycle

Tricycle 2
SP = 2200
L%= 12%
we are using the same 7 by 7 method,, but this time for every 12 % L, we decrease 12 rs
 CP                      SP
100                      88
 ?                        2200

2200*100
      88
= 220000/88
= 2,500
this is the cost of Tricycle 2

I hope this helps,,

Answer 2

Answer: rupees 2000and 2500

Step-by-step explanation:

Both tricycle price = 2200

A) profit =10%

So,

2200*100

_________ = ( now keep 100 aside)

100+10 2200

______ = 20

110

Now, take 100

20*100=2000

B) loss=12%

So,

2200*100 2200

________ = _______ =2.5

100-12 88

Now take 100

2.5*100=2500
