Question

Amal bought 5biscuits 9 cakes and 6chocolates and rajan bought 6biscuits 12chocolates and 18cakes for an amount which was half more than amal had paid .what percentage of total amount paid by amal for biscuits

Answer 1

Answer:

For biscuits, Amal paid 50% of the amount

Step-by-step explanation:

Let Amal bought 5 biscuits, 9 cakes and 6 chocolates in Rs. x

Let Rajan bought 6 biscuits, 12 chocolates and 18 cakes in rs. y

Then, according to the question

y = x + x/2

or, y = 3x/2

If the items Amal bought is multiplied by 2 then the Rs paid will also be multiplied by 2

i.e. 10 biscuits, 18 cakes and 12 chocolates will cost 2x Rs.

Subtracting the above from Rajan's items

We get that 4 biscuits cost Rs.

=2x-y

= 2x - 3x/2

=x/2 Rs.

which is 50% of x
