Let the selling price for the umbrella is P.
Cost price for the umbrella is Q.
Now from question
Q - 2P/3 = 10% of Q.Correct Option: C
Let the selling price for the umbrella is P.
Cost price for the umbrella is Q.
Now from question
Q - 2P/3 = 10% of Q.
⇒ P = (3/2)(Q - 10% of Q)
⇒ P = (3/2) x (90/100) x Q
∴ P = 1.35 x Q.
So % profit = [(1.35 x Q - Q)/Q]x100 % = 35 % profit.

Let the actual price of per kg of wheat = ₹ . 100
Then, selling price = 110% of 100 = ₹ 110
Now, shopkeeper sell 20% less than actual weight so cost price to shopkeeper will be = 80% of 100
= (80 x 100)/100
= ₹ 80Correct Option: C
Let the actual price of per kg of wheat = ₹ . 100
Then, selling price = 110% of 100 = ₹ 110
Now, shopkeeper sell 20% less than actual weight so cost price to shopkeeper will be = 80% of 100
= (80 x 100)/100
= ₹ 80
Hence, required profit gained by shopkeeper = [(110 - 80)/80] x 100
= (30/80) x 100
= 37.5%

SP. of first hen = (115/100) x 500 = Rs. 575
SP of second hen = (95/100) x 500 = Rs. 475
Total SP = 575 + 475 = Rs. 1050
Total CP = 2 x 500 = Rs. 1000
Gain = SP - CP = (1050 - 1000) = Rs. 50Correct Option: A

Gain = SP - CP = (1050 - 1000) = Rs. 50
Gain percentage = (50/1000) x 100 = 5%

CP of 12 pencils = Rs. 12
∴ SP of 10 pencils = Rs.12
⇒ SP of 12 Pencils = (12/10) x 12 = Rs.14.40Correct Option: A
CP of 12 pencils = Rs. 12
∴ SP of 10 pencils = Rs.12
⇒ SP of 12 Pencils = (12/10) x 12 = Rs.14.40
∴ Gain per cent = {(14.40 - 12)/12} x 100 = 20%

Total CP = (3.75/12) x 800 = (375/1200) x 800 = Rs. 250
Total SP = (1/2) x 450 + (2/5) x 350 = 225 + 140 = Rs. 365Correct Option: B
Total CP = (3.75/12) x 800 = (375/1200) x 800 = Rs. 250
Total SP = (1/2) x 450 + (2/5) x 350 = 225 + 140 = Rs. 365
Gain = 365 - 250 = Rs. 115
Gain percentage = (115/250) x 100% = 46%
