From the question it is given that,

Number of shares = 500

Then, nominal value of each share = ₹ 50

So, investment by Mahesh = ₹ (50 × 500)

= ₹ 25,000

Mahesh sold shares at premium = (1/3) × 500

= 166.5

Market value of a share with premium = ₹(50+20) = ₹70

Then, value of 200 shares = ₹(70 ×166.5)

= ₹11,655

Shares sold at discount = 500 - 166.5=₹333.5

Then, market value of a share with discount =₹50 - ₹5=₹45

Value of 333.5 shares =₹(45 × 333.5)

=₹15007.5

By adding value of 166.5 shares and value of 333.54 shares we get the total money received by selling his shares,

= 14,000+15007.5

= ₹ 29007.5

Difference in selling price and cost price =₹( 29007.5 - 30,000)

=₹992.5

Therefore, Mahesh gained ₹992.5
