=》》》♧ Let those friends were having Rs x and y with them. Using the information given in the question, we obtain

x + 100

= 2(y − 100) x + 100

= 2y − 200 x − 2y

= −300 (i) And, 6(x − 10)

= (y + 10) 6x − 60

= y + 10 6x − y = 70 (ii)

Multiplying equation (ii) by 2, we obtain

12x − 2y = 140 (iii)

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

11x = 140 + 300 11x

= 440 x = 40

Using this in equation (i), we obtain

40 − 2y

= −300 40 + 300

= 2y 2y

= 340 y

= 170

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