Kiran is 24 years older than Rakesh. 10 years back Kiran’s age was five times the age of Rakesh. Find their ages.

The age of Rakesh = 18

   The age of Kiran = 42

Let  

The age of Rakesh = x

The age of Kiran     = 24 + x

10 years back:

Age of Rakesh = x - 10

Age of Kiran     = 24 + x -10

⇒ x + 24 + x = 5 [ 14 + x ]  

⇒ 2x + 24     = 70 + 5x

⇒ 3x = 46

⇒ x = 18

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
