Explanation

First, let's calculate the total cost price (CP) including the sales tax:

CP = Rs. 250 (cost) + 15% of Rs. 250 (sales tax)

= Rs. 250 + (15/100) × Rs. 250

= Rs. 250 + Rs. 37.50

= Rs. 287.50

Now, let's calculate the profit:

Profit = Selling Price (SP) - Total Cost Price (CP)

= Rs. 315 - Rs. 287.50

= Rs. 27.50

So, Ali made a profit of Rs. 27.50!

Explanation

To find the volume of the book, we need to multiply the length, width, and thickness:

Volume = Length × Width × Thickness

= 19 cm × 12 cm × 3 cm

= 684 cm³

So, the volume of the book is 684 cm³!

Explanation

When boiling multiple eggs together, the cooking time doesn't increase linearly with the number of eggs. 

As long as the eggs are not stacked on top of each other and are fully submerged in water, the cooking time remains roughly the same.

So, it will still take 2 minutes to boil 5 eggs together!

Explanation

Since he spent 88% of his income, he has 12% of his income left (100% - 88% = 12%).

We know that 12% of his income is Rs. 2160, so we can set up the equation:

12% of x = 2160

To solve for x, we can convert the percentage to a decimal by dividing by 100:

0.12x = 2160

Now, divide both sides by 0.12:

x = 2160 / 0.12

x = 18000

So, his income is Rs. 18000!

Q: Write only three qualities of a good office manager?

Ans:

1. Strong communication skills

2. Effective organizational abilities

3. Leadership and decision-making capabilities

Explanation

Machine A can complete the job in 8 hours, so its work rate is 1/8 of the job per hour.

Machine B can complete the job in 12 hours, so its work rate is 1/12 of the job per hour.

When they work together, their combined work rate is the sum of their individual work rates:

(1/8 + 1/12) of the job per hour

To add these fractions, we need a common denominator, which is 24. So we get:

(3/24 + 2/24) = 5/24 of the job per hour

Since they can complete 5/24 of the job in 1 hour, they can complete the entire job (1) in:

24/5 = 4.8 hours

So, the correct answer is: 4.8 hours!
