Hexaware Percentages Quiz 1

8 : 5 = 8/5

Percentage = 8/5 * 100 = 160%

Given, Ashita got 85 and failed by 15.

The minimum marks = 85 + 15 = 100

Minimum % to pass = 40%

Therefore, total marks = 40/100 = 100

40 = 10000

Total marks = 250

Total passing marks = 41 + 3 = 44

Let maximum marks be m

Then, 40% of m = 44

=>40m/100 = 44

=>40m = 4400

=>m = 110

Given, total runs = 58

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

Runs scored by running = 58 – 36 = 22

Percentage = 22/58*100 = 37.93%

Let the initial number be n.

The number developed = 115% of 85% of n

= 115/100 * 85/100*n = 0.97n

Now,  n – 0.97n = 15

=>0.03 n = 15

=>n = 500

Let his income be x

He contributed 10% of x = 10/100 * x = x/10

Remainder = x – x/10 = 9x/10

Money deposited in bank = 25% of 9x/10

= 25/100 * 9x/10 = 9x/40

9x/10 - 9x/40 = 2100

27x/40 = 2100

x = 2100*40 / 27

x = 3111.11

Money spent = (100 – 51) of 15000

= 49% of 15000

= 49/100*15000 = 7350

Commission up to 85000 = 85000 * 2/100 = 1700

Again after 85000,

Commission: Bonus = 2 : 1 = 2x : x

Therefore, bonus = (2500-1700) * 1/3 = 800*1/3 = Rs. 266.66

krishna spends 15% on rent = 85% of 30000

= (85 * 30000) /100 = 25500

Remaining amount = 25500

Now spends 30% on food = 70% of 25500

= (70*25500) /100 = 17850

Remaining = 17850

Now saves 60% of remaining = (60* 17850) /100

= 10710

Let x% of 55 = 21

Therefore, x/100*55 = 21

55x = 2100

x = 38.18%
