Question

6. The price of a dozen bananas fell down by 15%
over the week. If Rajat saved ₹30 on 120 bananas,
find the price of 6 dozen bananas.​

Answer 1

Step-by-step explanation:

dozen of bananas = 15% down

Rajat saved = 30/- on 120 bananas

so, 15/100× X = 30

x = 20 × 30/3

x = 200/- --------> cost of 120 bananas in 15% discount ..

if 120 bananas = 200/-

then 6 bananas = x

120× = 600×6

x = 5×6

x = 30/-

hence 6 bananas in 15% discount is 30/- ..:);)

Answer 2

Answer:

102

Step-by-step explanation:

Let X be the actual price of 120 bananas.

so, we have 15% of X is Rs.30.( as he saved rs.30 on120 bananas)

$\frac{15}{100}$*X=30

therefore X=200

Now after discount price of 120 bananas is 200-30=170

so if 120 bananas(10 dozen)  cost 170 rupees

so 12 bananas( 1 dozen ) cost 17 rupees.

hence 6 dozen bananas cost 17*6=102.

hope this helps.
