300
400
500
600
700
Option A
Let CP= Rs.x
profit = 2 loss
ie) 1000- x= 2( x-800)
=>3x=1800
=>x= CP= Rs.300

2. A vendor purchased 50 kg of tomatoes from Farm 1 at Rs. 20 per kg and 30 kg of tomatoes for Rs. 22 per kg. He mixed two farms tomatoes for sale..At what rate the vendor should be sold to get 10% profit?
24
27
34
22
23
Option E
CP of two farms tomatoes= Rs.( 50 *20 + 30 *22)
= Rs. 1660
CP of 1 kg tomatoes= 1660/(50+30) =1660/80 = Rs.20.75
Profit % = 10%
=>SP of 1 kg tomatoes= 20.75 * 110/100
= Rs.23 ( approx)

4800
Option B
Let the marked price be Rs.x
S.P = x*90/100 * 108/100 = Rs.4860
=> x= 4860*100 *100/ 90*108
=> x= Rs.5000
