The average weight of 40 students in a class is 75 kg. By mistake the weights of two students are read as 74 kg and 66 kg respectively instead of 66 kg and 54 kg. Find the corrected average weight of the class

- a)73.50 kg
- b)74.50 kg
- c)75.50 kg
- d)76.50 kg
- e)None of these

Correct answer is option 'B'. Can you explain this answer?

Divey Sethi answered • 1 hour ago

Answer – b) 74.50 kg Explanation : Weight of 40 students = 40*75 new weight = 40*75 – 74 – 66 + 66 + 54 = 40*75 – 20 so new average =( 40*75 – 20)/40 = 74.50 kg

1 litres = 1000 cm

9 litres = 9000 cm

Volume of cylinder = πr^{2}h

22/7*7*7*h = 11000

h = 9000*7*4/22*7*7 = 233.8 cm

9 litres = 9000 cm

Volume of cylinder = πr

22/7*7*7*h = 11000

Ayshwarya R Srivatsa answered • 12 hours ago

Let Suji age be x yr
And Kiran age be 5x yr
In 10 yrs, Suji will be x+10 and Kiran be 5x+10
Thus, According to condition
5x+10=3(x+10)
5x+10=3x+30
5x-3x=30-10
2x=20
x=10
Thus, Kiran age is 5x=5(10)=50
Hence, Kiran age is 50 yrs and Suji age is 10 yrs.

A smaller triangle is having three sides. Another big triangle is having sides exactly double the sides of the smaller triangle. Then what is the ratio of Area of Smaller triangle to Area of the Bigger triangle?

- c)1:4
- d)4:1
- e)Cannot be determined

Correct answer is option 'C'. Can you explain this answer?

Bank Exams India answered • 12 hours ago

Smaller triangle sides = a, b, c

Area= √s(s-a) (s-b) (s-c);

s=a+b+c/2

= √(a+b+c)(b+c-a)(a+c- b)(a+b-c)/4

Bigger triangle =2a, 2b, 2c

Area = √(a+b+c)(b+c-a)(a+c- b)(a+b-c)

Ratio = 1:4

Area= √s(s-a) (s-b) (s-c);

s=a+b+c/2

= √(a+b+c)(b+c-a)(a+c- b)(a+b-c)/4

Bigger triangle =2a, 2b, 2c

Area = √(a+b+c)(b+c-a)(a+c- b)(a+b-c)

Ratio = 1:4

3x – x = 32

x = 16

1/16 + 1/48 = 4/48

1/16 + 1/48 = 4/48

Time taken to fill the tank = 48/4 = 12 minutes

x = 12

Area of the original rectangle = 3x * 2x = 6x²

Area of the original rectangle = 6 * 144 = 864 m²

On solving (i) and (ii), we get *x* = 4.

Wizius Careers answered • 12 hours ago

A and B can fill tank in (1/20 + 1/30) = 1/12 so 12 minutes

But it took 3 more minutes, this means the tank got full in 12+3 = 15 minutes

So (1/20 + 1/30 – 1/x) = 1/15

Solve, x = 60

But it took 3 more minutes, this means the tank got full in 12+3 = 15 minutes

So (1/20 + 1/30 – 1/x) = 1/15

Solve, x = 60
