Answer:
ON SELLING 30 BAGS OF ONION
HIS PROFIT IS 30×200=6000
ON SELLING 50 BAGS OF ONION HIS LOSS=50×30=1500
TOTAL PROFIT =6000_1500=4500
ON SELLING 40 BAGS OF POTATOES
HIS LOSS=40×50=2000
IN ORDER TO MAKE NO PROFIT OR LOSS HIS LOSS SHOULD BE EQUAL TO HIS PROFIT
SO
NO OF BAGS×200=2000
NO OF NAGS=2000/200=10
