price of a dozen bananas fell down by 15% over the week.if rajat save 30 rupees on 120 bananas find the price of 6 dozen Bananas ​

Answer 1

Given: Price of a dozen bananas fell down by 15% over the week.

To find: If rajat save 30 rupees on 120 bananas find the price of 6 dozen Bananas ​.

Solution:

• Now we have given that price of dozen of bananas fell down by 15%.

• Rajat saved Rs 30 on 120 bananas, so:

• Let the cost of 120 bananas in 15% discount be A, then:

                  15/100 x A = 30

                  A= 20 x 30/3

                  A = 200

• Now if 120 bananas = Rs 200 then for 6 bananas, we have:              

                  120 x y= 200 x 6

                  y = 10

                  y = Rs 10

Answer:

         So, the price of 6 dozen Bananas is Rs 30.

Answer 2

Answer:

102

Step-by-step explanation:

Let us assume the actual price of 120 bananas be 'x'

Given: he saved rs.30 on 120 bananas.

15% of x=30

x= 30* 100/15=200

SInce, he got 120 bananas for Rupees 30 less due to discount

we say that he bought 120 bananas(10 dozens of bananas) for 200-30=170

i.e.120 bananas(10 dozens) cost =rupees 170

1 dozen cost = 17

6 dozen cost = 17*6=102

hence answer is Rs.102
