Explanation

Let's say the two numbers are x and y.

Given:

x + y = 24 ... (1)

x - y = 6 ... (2)

Adding (1) and (2):

2x = 30

x = 15

Substituting x in (1):

15 + y = 24

y = 9

The numbers are 15 and 9.

Explanation

Let's say the original number is x.

Given:

1/3 of x + 16 = 2 1/3 of x

1/3x + 16 = 7/3x

Multiply both sides by 3:

x + 48 = 7x

48 = 6x

x = 48/6

x = 8

Explanation

Let's say the cost price (CP) of the washing machine is x.

Given that the GST rate is 17%, the selling price (SP) would be:

SP = x + 0.17x

SP = 1.17x

Given that SP = Rs 15,912:

1.17x = 15912

x = 15912 / 1.17

x = 13600

Explanation

Let's say the number of plants in each row is x.

Since there are as many rows as there are plants in each row, the total number of plants is x * x = x².

Given that the total number of plants is 625:

x² = 625

x = √625

x = 25

Explanation

5% of 16,000 = 800, so increase = 800.

New population = 16,000 + 800 = 16,800.

A percentage increase means adding the calculated percent value to the original number.

Explanation

The perimeter of a rectangle is given by:

P = 2(length + breadth)

Given:

P = 28 cm

Breadth = 6 cm

28 = 2(length + 6)

14 = length + 6

length = 8 cm

Explanation

640 × 1.50 = 960

So, the total cost of 640 photocopies at Rs. 1.50 each is Rs. 960.
