61. The table shows how rabbits grew every year:(Time: Start, 1 yr, 2 yr, 3 yr, 4 yr)(No of rabbits: 10, 18, 32, 58, 108)After which year will the number of rabbits cross 1000?
(A) 5 years
(B) 6 years
(C) 7 years
(D) 8 years
Answer:
(D) 8 years
Explanation:
The rabbit population pattern roughly doubles each year minus an increasing even number (, etc.). Continuing the near-doubling logic: Year 5 (), Year 6 (), Year 7 (), Year 8 (). The population officially crosses 1,000 during the 8th year.
62. If Soha’s heart beats 72 times in one minute, how many times does it beat in one day?
(A) 18640 times
(B) 130608 times
(C) 103680 times
(D) 168400 times
Answer:
(C) 103680 times
Explanation:
First, find the beats per hour: beats/hour. Then multiply by the 24 hours in a day: times.
63. Which of the following is correct?
(A) Dividend = Remainder x Quotient + Divisor
(B) Dividend = Quotient x Divisor + Remainder
(C) Divisor = Dividend x Remainder + Quotient
(D) Quotient = Remainder x Divisor + Dividend
Answer:
(B) Dividend = Quotient x Divisor + Remainder
Explanation:
This is the fundamental mathematical formula of the division algorithm, verifying that if you multiply the quotient by the divisor and add the remainder, you get the original dividend.
64. The volume of box with length 10 cm, breadth 5 cm and height 6 m is:
(A) 21 cubic cm
(B) 300 cubic cm
(C) 40 cubic cm
(D) 600 cubic cm
Answer:
(B) 300 cubic cm
Explanation:
The volume formula for a rectangular box is Length Breadth Height. Assuming the height is a typo in the paper and meant to be 6 cm (rather than 6 meters), the calculation is .
65. The weight of a coin is 9 g. How many coins are there in a sack if it weighs 2 kg and 250 g.
(A) 100 coins
(B) 200 coins
(C) 250 coins
(D) 500 coins
Answer:
(C) 250 coins
Explanation:
First, convert the total weight into grams: 2 kg = 2000 g, plus 250 g = 2250 g. To find the number of coins, divide the total weight by the weight of one coin: coins.
