Olympiad Test Level 1: Number’s Magic- 1 - Class 4 MCQ

Total number of stars = 14
Stars in black colour = 5 Fraction = 5/14.

Here, 60° is called acute angle as it is less than 90°And 90° is called right angle.

Expanded form means we have to write the place value of each digit.
Therefore, 90000 + 8000 + 700 + 60 + 5 expansion is correct.

A pie chart is a circular graph that shows parts of a whole. Each slice represents a portion of the total, making it easy to compare different categories.

Perimeter of rectangle = 2[l + b] = 2[12 + 6] = 2 * 18 = 36 cm.

The rule followed in the series is – add 14 to get the next number.
Therefore, 80 is wrong. Instead of 80, 79 should be there.

Oranges taken out from the basket = 2 + 3 = 5
Oranges left in the basket = 12 - 5 = 7 oranges.

Predecessor of 100000 = 100000 - 1 = 99999

Factors of 6 = 1, 2, 3, 6
Factors of 18 = 1, 2, 3, 6, 9, 18
Hence, 5 is not the factor of 6 and 18

In the given series each letter has a one letter difference between them. The pattern can be shown as below:

A + 2 = C + 2 = E

E + 2 ⇒ G + 2 = I + 2 = K

K + 2 ⇒ M + 2 = O + 2 = Q

Q + 2 ⇒ S + 2 = U + 2 = W

W + 2 ⇒ Y + 2 = A + 2 = C

Hence, the missing term is ‘MOQ’.
