**Problem: TOMATO Objective 01**

A worker suffers a %Â cut in wages. He regains his original pay by obtaining a rise of

(A) %

(B) Â %

(C) %

(D) %

Solution:

Let the original pay be Rs. (freedom of choice of the unit).

Then, new pay % of Rs.Â Â Rs. % of Â xÂ = Rs.Â \( \frac{4x}{5}\)

and, decrease in payÂ % of Rs. xÂ =

Therefore, to regain the original pay, there must be a 20 % increase in the new pay and this increase has to beÂ done WITH RESPECT TO THE NEW PAY*Â *as in this case, the new pay obtained in the precious case ( which isÂ ) becomes theÂ ORIGINAL PAY*Â *for the tabulation of the new pay in the second case (when the pay is again increased).

This implies that the required increase in pay must be times 100 % Â = 25 %

Therefore, option (C) is the correct option.
