Question

A builder offers each flat worth 60 lakh for sale at a discount of 15% with further incentive of 10
lump sum payment. How much did a customer pay if he paid the entire amount?​

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

Customer paid 45.9 lakh if he paid the entire amount.

Step-by-step explanation:

Worth of each flat = 60 lakh

Builder offers a discount of 15% with further incentive of 10% on lump sum payment.

We will use the formula of equivalent discount :

$CP=SP(1-\frac{d_{1} }{100})\times (1-\frac{d_{2} }{100})$

SP = Selling price 60 lakh

d1 = First discount 15%

d2 = Second discount 10%

Now put the values in to the formula

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

                = 60lakh(1 - 0.15) × (1 - 0.10)

                = 60 lakh(0.85)(0.90)

               = 60 lakh × 0.765

               = 45.9 Lakh

Customer paid 45.9 lakh if he paid the entire amount.
