40x/100 = y

=>(40x)/(100 * 100) = y/100  [multiplying 1/100 in both side]

=>(40 * 40x)/(100 * 100) = 40y/100   [multiplying 40 in both side]

=>16x/100 = y % of 40

=>y% of 40 = 16% of x

Total vote = 35 + 15 + 50 = 100

Percentage of the vote, Ankita got = (50/100) x 100 = 50%

Increase in 10 years = (262500 - 175000) = 87500.

Increase percentage of population = (87500 / 17500) x 100 = 50%

So, required average = (50/10)% = 5%

Excess of Atul’s height over Avik = [15/ (100-15)] *100

= 15/85*100

= 17.64%

Let, the amount of taxable purchases be x.

So, 6% of x = 30/100

=> x = (30/6) = 5

Cost of tax free items = 25 - (5 + 0.30) = 19.70

Given, the population of a city two years back = 23, 00,000

Population increased in one year = 5% of 2300000 = 115000

Therefore, population after one year = 2300000 + 115000 = 2415000

Population increased in second year = 4% of 2415000 = 96000

Hence, current population = 2415000 + 96000 = 2511000

Ankita spends = (100 - 25)% = 75%

She spend total = 15000 x (75/100) = 11,250

Given, total runs = 65

Runs scored by fours and sixes = (3*4) + (4*6) = 12 + 24 = 36

Runs scored by running = 65 – 36 = 29

Percentage = (29/65)*100 = 44.6%

Let x% of 55 = 21

Therefore, (x/100)*55 = 21

=>55x = 2100

=>x = 38.18%

Let the original price be 100

Reduced price = 84

Increment on 84 = 12

Increment on 100 = 12/84 * 100 = 14.28%
