Explanation

A's capital: B's capital

20000 : 40000 = 1 : 2

Since the time period is fixed, the profit is distributed in the ratio of capital 1: 2

Profit of A = (1/3) * 33,000 = Rs. 11,000

Salary of A = Rs. (15000 – 11000)

= Rs. 4000

Explanation

Solution

total balls

white+red = 70+30=100

so white probability=70/100

=7/10

so red possibility = 30/100

=3/10

so to check probability then add them

=7/10+3/10

=10/10

=1

hense the answer is 1

Explanation

To find the fraction of green marbles, we need to calculate the total number of marbles first.

Sara has:

- 5 red marbles

- 3 green marbles

- 2 blue marbles

Total marbles = 5 (red) + 3 (green) + 2 (blue) = 10 marbles

Next, we determine the fraction of green marbles out of the total marbles:

Fraction of green marbles = Number of green marbles / Total number of marbles

Fraction of green marbles = 3 / 10

Explanation

To find the average, add up all the numbers and divide by the total count.

Step 1: Calculate the sum

Sum = 0 + 0 + 4 + 10 + 5 + 5

= 24

Step 2: Calculate the average

Average = Sum / Count

= 24 / 6

= 4

Explanation

A boy walked for =1/2 hours

 got a bus for= 1/3  hours

Total time = 1/2+1/3

                 = (2+3)/6 

                   =5/6

Explanation

4th day of the month is Sunday.

So, (4 + 7) = 11th day is Sunday

(11 + 7) = 18th day is Sunday

(18 + 7) = 25th day is Sunday

So 6th day before the 30th day is 24th

If 25th is Sunday, 24th is Saturday

Explanation

5000m is represented by 100cm

Therefore, 1m will be represented by 100÷5000cm

Therefore,750m will be represented by 100÷5000×750=15cm.

Explanation

Given the average of 10, k, and 30 is 21:

(10 + k + 30) / 3 = 21

Multiply both sides by 3:

10 + k + 30 = 63

Combine constants:

40 + k = 63

Subtract 40 from both sides:

k = 23

Explanation

 (15 + 14 + 13 + 12 + 6) / 5

= 60 / 5

= 12
