Answer 1

The customer paid 45.9 lakhs if he paid the entire amount.

Step-by-step explanation:

Cost of flat = 60 lakh

Discount offered by the builder = 15%

On paying the lumpsum anount the further discount offered = 10%

Therefore, the amount paid

$=(60-60\times\frac{15}{100})(1-\frac{10}{100}$

$=60\times (1-0.15)(1-0.1)$

$=60\times 0.85\times 0.9$

$=45.9$ Lakhs

Answer 2

The customer paid=45.9 lakh

Step-by-step explanation:

Worth of flat=Rs 60 lakh

First discount=$d_1=$15%=0.15

Second discount=$d_2=10$%=0.10

We know that

Amount =$C.P\times (1-d_1)(1-d_2)$

Where C.P=Cost price

$d_1=$first discount

$d_2$=Second discount

Using the formula

Then, we get

Amount paid by customer =$60(1-0.15)(1-0.10)=45.9 Lakh$

Hence, the customer paid=45.9 lakh
