Geeta saved Rs. 300 and Meeta saved Rs. 450. They each spend half of their money on a trip to the mall, so Geeta spends Rs. 300/2 = Rs. 150 and Meeta spends Rs. 450/2 = Rs. 225.

After spending money on the trip, Geeta will have Rs. 300 – Rs. 150 = Rs. 150 left. After spending money on the trip, Meeta will have Rs. 450 – Rs. 225 = Rs. 225 left.

When they join their money, the total amount they will have is Rs. 150 + Rs. 225 = Rs. 375.

To buy a Barbie doll that costs Rs. 660, they need Rs. 660 – Rs. 375 = Rs. 285 more.

1. To calculate the perimeter of a rectangle, we add the lengths of all four sides. In this given question, the length is 12 cm and the breadth is 8 cm.

Perimeter of the rectangle = 2 × (Length + Breadth)

Perimeter = 2 × (12 cm + 8 cm)

Perimeter = 2 × 20 cm

Perimeter = 40 cm

So, the perimeter of the rectangle is 40 cm.

To find the area of a rectangle, we multiply the length by the breadth.

Area of the rectangle = Length × Breadth

Area = 12 cm × 8 cm

Area = 96 cm²

So, the area of the rectangle is 96 square cm.

2. A quadrilateral with one pair of opposite sides parallel and equal in length, and all angles being right angles, is called a rectangle. In other words, if a quadrilateral has two pairs of opposite sides that are parallel and equal in length, it is a rectangle.

To find the probability of selecting a fruit-flavored candy, we need to determine the ratio of fruit-flavored candies to the total number of candies using the given information.

Given that the jar contains 20 candies, with 12 fruit-flavored and 8 chocolate-flavored candies, we can calculate the probability using the basic probability formula:-

Probability of selecting a fruit-flavored candy = Number of fruit-flavored candies / Total number of candies

Probability = 12 / 20

Simplifying the fraction, we get:

Probability = 3 / 5

Therefore, the probability is 3/5 or 0.6 (60% chance of selecting a fruit-flavoured candy).

This problem is based on simple addition in maths.

If I have 3 apples and get more,I will have 5 Apples!

As 3+2=5.

This can be also solved using fingers.

First off,Make a fist by closing all your fingers.

Now, Open three of your fingers.

Now,If someone tells you to open 2 more of your fingers, at last when your count your total “opened fingers”

The answer will be 5.

Same as the apples question!

In general we can say that there are 2n numbers between the squares of the numbers n and (n + 1).

Here,The given numbers are 99 and 100.So,

Here, n = 99 and (n + 1) = 100

Clearly n=99
Now, 2n =2×99=198

⇒ There are 198 non-perfect square numbers between the squares of the numbers 99 and 100.
