Raju, Sohan, and Tina are partners in a firm sharing profits and losses in the ratio of 2 : 2 : 1. Tina is guaranteed a minimum amount of ₹40,000 as a share of profit every year. Any deficiency arising on that account shall be borne by Raju. If profit of the firm for the year ended 31st March, 2023 is ₹1,60,000, Raju will bear a deficiency of:
Step 1: Calculate Tina's profit share. \[ \text{Tina's share of profit} = \frac{1}{5} \times 1,60,000 = ₹32,000. \] Step 2: Determine the deficiency. \[ \text{Deficiency} = ₹40,000 - ₹32,000 = ₹8,000. \] Since Raju is responsible for the deficiency, he will bear ₹8,000.

A ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:
(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?
