Answer: Option C

Explanation:

Let they receive A, B & C Rs. respectively.

Now, A = (B + C) / 2

or, 2A = B + C - - - - - - - - - - (i)

Again, B = (A + C) / 4

or, 4B = (A + C)

or, 4B = (B + C) / 2 + C

or, 4B = B/2 + C/2 + C

or, 4B - B/2 = 3C/2

or, 7B/2 = 3C/2

or, B = 3C/7 - - - - - - - (ii)

Now, 2A = 3C/7 + C [from (i)]

or, 2A = 10C/7

or, A = 5C/7 - - - - - - (iii)

From (ii) and (iii),

B : C = 3 : 7

C : A = 7 : 5

So, A : B : C = 5 : 3 : 7

A will receive = 5 / (5 + 3 + 7) × 5625 = 1875 Rs.

B will receive = 3 / (5 + 3 + 7) × 5625 = 1125 Rs.

C will receive = 7 / (5 + 3 + 7) × 5625 = 2625 Rs.

Answer: Option D

Explanation:

Price after 15% discount = 100 - 15 = 85 TK.

Price after 15% raise = 100 + 15 = 115

Price difference = 115 - 85 = 30 TK.

If price difference is 30 TK. then original price is 100 TK.

If price difference is 60 TK. then original price is 100 x 60 / 30 = 200 TK
