Answer 2

Given :

• One says, "give me hundred, friend! I shall then become twice as rich as you"

• The other replies, "If you give me ten then, I shall be six times as rich as you".

To Find :

• Respective capital of friends?

Solution :

• Let those friends were having Rs x and y with them.

† Using the information given in the question, we obtain

$\\:\implies\sf \: x + 100 = 2 (y - 100)$

$:\implies\sf \: x + 100 = 2 y - 200$

$:\implies\sf \: x - 2y= - 300 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: - ( \: i \: )$

$:\implies \sf \: And, \: 6 (x - 10) = (y + 10)$

$: \implies \sf \: 6x - 60 = y + 10$

$: \implies \sf\: 6x - y = 70 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: - (ii)$

• Multiplying equation (ii) by 2, we obtain

$\\ : \implies \sf \: 2x - 2y = 140 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: - (iii)$

• Subtracting equation (i) from equation (iii), we obtain

$\\ : \implies \sf \: 11x = 140 + 300$

$: \implies \sf \: 11x = \: 440$

$: \implies \sf \: 11x = \: 40$

• Using this in equation (i), we obtain

$\\: \implies \sf \: 40 + 300= 2y$

$: \implies \sf\:2y = 340$

$: \implies \sf\:y = -340$

$: \implies \sf\: 40 - 2y = -300$

Therefore, those friends had Rs 40 and Rs 170 with them respectively.
