651. If there are 27 students in class and 7 girls are more than boys. How many total girls are in class?

Check answer and explanation

Answer: 17

Explanation Total students = 27 Since 7 more girls than boys, let's represent the number of boys as x. Number of girls = x + 7 Total students = Boys + Girls 27 = x + (x + 7) Combine like terms: 27 = 2x + 7 Subtract 7: 20 = 2x Divide by 2: 10 = x Number of boys = 10 Number of girls = 10 + 7 = 17 Therefore: Total girls in the class = 17 Last verified on 06-03-2026

652. A group generated by one of its elements, is called?

Check answer and explanation

Answer: A cyclic group

Explanation A group generated by one of its elements is called a cyclic group. This means that the group can be generated by repeatedly applying the group operation to a single element , called the generator. In other words, all elements of the group can be expressed as powers of the generator.

653. The side of an isosceles right triangle of hypotenuse 5 2 ​ cm is :

Check answer and explanation

Answer: 5cm

Explanation Sides other than hypotenuse of an isosceles triangle are equal. Let the other two sides be x each. Using pythagoras theorem x 2 + x 2 = ( 5 2 ​ ) 2 2 x 2 = 5 0 ⇒ x 2 = 2 5 ⇒ x = 5 c m So the other two sides are 5 c m each.

654. 7/4 ÷ [77/8 ÷ 30/5] = _____?

Check answer and explanation

Answer: 12/11

Explanation 7/4 ÷ [77/8 ÷ 30/5 ] 7/4 ÷ [77/8 × 5/30] = 7/4 ÷ 77/48 = 7/4 × 48/77 = 12/11

655. 4 boys ran 60km each in 6 hours, distance covered by 1 boy in 1 hour?....

657. A and B can together finish a work in 30 days. They worked together for 20 days and then B left after 20 days. A finished the worked. In how many days A alone can finish the work?

Check answer and explanation

Answer: 60

Explanation Amount of work done by A and B in 1 day = 1/30 Amount of work done by A and B in 20 days = 20 × (1/30) = 20/30 = 2/3 Remaining work – 1 – 2/3 = 1/3 A completes 1/3 work in 20 days Amount of work A can do in 1 day = (1/3)/20 = 1/60 => A can complete the work in 60 days

658. The angle of elevation of the sun, when the length of the shadow of a tree is equal to the height of the tree is?

Check answer and explanation

Answer: 45 degree

Explanation Let's denote the height of the tree as h and the length of the shadow as h (since they are equal). Step 1: Recall the tangent function tan(θ) = opposite side (height of the tree) / adjacent side (length of the shadow) tan(θ) = h / h tan(θ) = 1 Step 2: Find the angle θ θ = arctan(1) θ = 45 degrees

659. Which letter is midway between the 8th letter from A and 7th letter from Z?

Check answer and explanation

Answer: N

Explanation Find the 8th letter from A : A (1), B (2), C (3), D (4), E (5), F (6), G (7), H (8) Find the 7th letter from Z (counting backward) : Z (1), Y (2), X (3), W (4), V (5), U (6), T (7) Find the midway letter between H and T : The alphabetical sequence from H to T is: H, I, J, K, L, M, N, O, P, Q, R, S, T This range has 13 letters. The middle letter is the 7th letter in this sequence. Counting: H (1), I (2), J (3), K (4), L (5), M (6), N (7)

660. The average of 5 quantities is 6. The average of 3 of them is 4. What is the average of remaining 2 numbers?

Check answer and explanation

Answer: 9

Explanation - Average of 5 quantities = 6 So, total sum of 5 = 5 × 6 = 30 - Average of 3 quantities = 4 So, total sum of 3 = 3 × 4 = 12 - Sum of remaining 2 = 30 − 12 = 18 - Average of remaining 2 = 18 ÷ 2 = 9
