Question

A trader gains Rs 20 , loses Rs 42 and then gains Rs 10 . Express algebraically the result of his transaction.​

Answer 1

There is a loss of Rs. 12 in this transaction.

Step-by-step explanation:

A trader gains Rs. 20, loses Rs. 42 and then gains Rs.10

Gain is represented by a positive sign and loss is represented by a negative sign.

So, above transactions can be represented by

= + 20 - 42 + 10

= 30 - 42

= -12

Result is a negative sign that means loss.

Hence, there is a loss of Rs. 12 in this transaction.
