Shopkeeper uses a weight of 800 g instead 1 kg, so that gain
= 1000 - 800 x100
800
= 200 /800 xl00 = 25%
His profit will be 25%.
= 1000 - 800 x100
800
= 200 /800 xl00 = 25%
His profit will be 25%.
CTET Maths MCQ - Percentage
Interest on Rs.22500 = 0.1 x 22500 = 2250
Charges for managing the concern = 60 x 12 = 720
If yearly profit is x, then B's share and A's share = (x/2)
∴(x/2)-2250 + 720
= (1/2)((x/2) -720 + 2250)
=> x = Rs. 9180.
Difference in % of votes = 57-43 = 14%
14% is represented by 420
Total number of votes = 420*(100/14)= 3,000
Growth rate of rat population in 3 months = 20 *(3/12) = 5%
Increase in first 3 months = 3200 x 1.05 = 3360
Also, net decrease in 3 months = 160
Rat population = 3360 - 160 = 3200
In the same way, after every 3 months, rat population remains the same
Hence, even after 3 x 8 months i.e., 2 years, the population is maintained
