The Cost price of 1 kg cashew nuts = Rs.700
Cost price of 50 g of cashew nut = (700*50)/1000 = 35
The selling price of 50 g cashew nuts = Rs.45
Profit = Selling Price -Cost price = 45-35 = 10
Profit % = Profit x 100/Cost price
Profit % = 10 x 100/35 = 28.57% profit
Hence, the answer is 28.57% profit

S1:S2=1:(3/4)
Since speed and time are inversely proportional. So t1:t2=3/4:1=3:4
Now,diff in time is 1.5 hrs. So,
4x-3x=1.5
X=1.5
So usual time is 3x = 4.5 hours
Option 4)
