1. Given,

Percentage of marks scored = 42%

Maximum marks = 2000

Let her marks be x

$x \div 2000 \times 100 = 42$

$x =( 42 \times 2000) \div 100$

=> 840

2. Given,

Total money = 4000

Percent of money spent = 20%

Let the money spent be x

so,

x x 100 = 20%

400

=> x = 20 x 4000 = Rs. 800

100

3. Given,

Total population = 155950

Percent of males = 58%

Let the no. of males be x

so,

x x 100 = 58

155950

=> x = 58 x 155950 = 29 x 3119 = 90451

100

So,no. of females = 155950 - 90451 = 65499

Speed = 80km/h

Decrease percent = 25%
