RRB Group D Mock Test - 23 - Question 26

A, B and C complete a piece of work in 30, 15 and 10 days respectively, while working individually. How much time will they take to complete the same work while working together?

Detailed Solution for RRB Group D Mock Test - 23 - Question 26

As per the formula,

Required days = (30 * 15 * 10) / (30*15 + 15*10 + 10*30) = 4500 / 900 = 5 days

RRB Group D Mock Test - 23 - Question 27

If 6 men and 8 boys can do a piece of work in 10 days while 26 men and 48 boys can do the same piece of work in 2 days, the time taken by 15 men and 20 boys in doing the same work will be

Detailed Solution for RRB Group D Mock Test - 23 - Question 27

Let work done by 1 man in 1 day be x

Also, work done by 1 boy in 1 day be y

Then, 6x + 8y = 1/10

Also, 26x + 48y = 1/2

Solving these two equations, we get,

x = 1/100 and y = 1/200

∴ 1-day work of 15 men and 20 boys = 15/100 + 20/200 = 1/4

=> 15 men and 20 boys can do the work in 4 days.

RRB Group D Mock Test - 23 - Question 28

If x/y = 4/5, find the value of (3x + 4y) / (4x + 3y)

Detailed Solution for RRB Group D Mock Test - 23 - Question 28

(3x + 4y) / (4x + 3y) = (3x/y + 4) / (4x/y + 3) [Dividing numerator and denominator by y]

= (3*(4/5) + 4) / (4*(4/5) + 3) = 32/31

RRB Group D Mock Test - 23 - Question 29

A triangle is having sides as 50m, 78m and 112m. Find the length of perpendicular on the side 112m.

Detailed Solution for RRB Group D Mock Test - 23 - Question 29

Here, a = 50m, b = 78m and c = 112m

S = (a + b + c)/2 = (50 + 78 + 112)/2 = 120m

∴ S – a = 120 – 50 = 70m

S – b = 120 – 78 = 42m

S – c = 120 – 112 = 8m

Now, Area = √[s*(s-a)(s-b)(s-c)] = √(120 * 70 * 42 * 8) = 1680m2

Also, Area = (base * perpendicular) / 2

1680 = (112 * P) / 2

=> P = 30m

RRB Group D Mock Test - 23 - Question 30

A circle and a rectangle have same perimeter. The side of rectangle are 18cm * 26cm. Find the area of circle.

Detailed Solution for RRB Group D Mock Test - 23 - Question 30

Perimeter of circle = Perimeter of rectangle

i.e., 2πr = 2*(l + b)

2πr = 2*(18 + 26)

2 * 22/7 * r = 88

=> r = 14

∴ Area of circle = πr2 = π*142 = 616cm2
