Answer»

There were 2 sold and 3 UNSOLD PRINTERS ⇒ he bought 5 printers and 20 monitors 

He sold 2 printers at a PROFIT of 2 × 2000 = Rs. 4000 

∴ Profit made on 75% of monitors = 49000 – 4000 = Rs. 45,000 

Profit on each monitor = $(\frac{{45000}}{{20}} \times \frac{{100}}{{75}} = {\rm{Rs}}.{\rm{\;}}3000)$

Cost price of 1 monitor = 3000 × $(\frac{{100}}{{20}})$ = Rs. 15000 

∴ Cost price of 20 monitors = 20 × 15000 = Rs. 3,00,000 

Cost price of 1 printer = 50% of 15000 = Rs. 7500 

∴ Cost price of 5 Printers = 5 × 7500 = Rs. 37500

Total cost = Rs. 3,00,000 + Rs. 37500 = Rs. 337500

Total revenue = 18000 × 15 + 9500 × 2 = Rs. 2,89,000

∴ He GOT loss = 337500 – 289000 = Rs. 48500
