Let the present age of Raman is A and the present age of Mohan is B.

(A – 5) = (B­­­­­­ – 5) × 3

A – 3B = -10      ----(1)

(A + 10) = (B + 10) × 2

A – 2B = 10      ----(2)

Solving equation (1) and (2)

A = 50 and B = 20

Difference in their present ages = 50 – 20 = 30

Selling price of TV = Rs.9400

Let loss suffered be Rs.M

Cost price of TV = M + 9400

Selling of other TV= Rs.10600

Gain = 2M

Cost price of other TV = 10600 – 2M

Then,

⇒ M + 9400 = 10600 – 2M

⇒ 3M = 1200

⇒ M = 400

∴ Cost price of an TV = 9400 + 400 = 9800

We know,

S.D = 15

As we know,

Sum of n natural numbers = n(n + 1)/2

⇒ Average of n natural numbers = (n + 1)/2

Given, Average of n natural numbers = 243

⇒ (n + 1)/2 = 243

⇒ n + 1 = 486

⇒ n = 486 – 1 = 485

⇒ 3n = 3(485) = 1455

∴ Average of 3n natural numbers = (1455 + 1)/2 = 1456/2 = 728
