2. 2820

4. 6375

Answer 1

Correct Answer - Option 3 : 3360

Given:

A and B bought chocolates in the ratio of 5 : 6.

Price of each chocolate is Rs.36

Ratio of Total number of chocolates after A and B get 35 extra chocolates each A : B = 8 : 9

Calculation:

Let the initial number of chocolates bought by A be 5X,

then, the initial number of chocolates purchased by B be 6X.

ATQ,

(5X + 35)/(6X + 35) = 8/9

⇒ 9 (5X + 35) = 8 (6X + 35)

⇒ 45X + 315 = 48X + 280

⇒ 3X = 35

⇒ X = 35/3

We know that A bought the fewer chocolates,

No. of chocolates bought by A = 5X + 35

⇒ 5 × 35/3 + 35

⇒ 280/3

Hence, the required amount = (280/3) × 36 

⇒ Rs. 3360
