Let amount of pulses sold at 8% profit be x.
So the amount of pulses sold at 18% profit is 50-x.
According to the question:
8% of x + 18% of (50-x) = 14% of 50
=> 8x/100 + 18(50-x)/100 = 7
=> 8x + 900 - 18x = 700
=> -10x + 900 = 700
=> 200 = 10x
=> x = 200/10 = 20 kg
50-x = 50-20 = 30kg
So amount of pulses sold at 18% profit is 30kg.
