Explanation

Length = 6m

Width = 5m

Height = 5m

Volume = L*W*H

=6*5*4

=120

Explanation

Probability = 5C2/7C2 = 10/21

Total number of balls = 2 + 3 + 2 = 7

∴ Number of ways of drawing 2 balls out of 7 = 7C2 = (7 × 6) / (2 × 1) = 42/2 = 21

Number of balls other than blue = 5

∴ Number of ways of drawing 2 balls out of 5 = 5C2 = (5 × 4) / (2 × 1) = 20/2 = 10

∴ Required Probability = 10/21

Explanation

• A man is standing upside down with his face towards the south.
• Normally, if a person stands upright facing south, their left hand points east and right hand points west.
• When flipped upside down, the directions of their hands do not change relative to their body.

Thus, the left hand will still point east

Explanation

Since the increasing average is 5 kg so the weight of each box would increase 5 kg So the total increase in weight = 5 x 3 = 15 kg   

Weight of new box to be = 98 + 14 = 104 kg

Explanation

Explanation

To determine the area of each part, we divide 15 acres by 3:

15 acres ÷ 3 = 5 acres

Therefore, the area of each part is 5 acres.

Explanation

Total monthly income of 16 persons is Rs. 80800.

Average monthly income = 

16

80800

​ =Rs 5050

Since the income of the one of them is 120 % of the average income,

Then his income is  

100

120​

 ×5050= Rs. 6060.

Explanation

We know that th CP of 1 toffee =₹1/5

SP of 1 toffee = ₹1/2

Since SP is more than CP it's Gain

Gain=SP−CP

=1/2−1/5

=3/10

∴Gain%=(Gain×100)/CP

=((3/10)×100)/(1/5)

=150% 

Explanation

15 men × 20 days = 300 man-days (total work)

Now, with 25 men:

300 man-days ÷ 25 men = 12 days

Explanation

Percent Value: 60%

Number: 240

60% of 240...

... is equivalent to multiplying them:
