• To find out how many one-fifths make a whole, we can think of it as dividing 1 by 1/5.
• This is the same as multiplying 1 by the reciprocal of 1/5, which is 5.
• So, 5 one-fifths will combine to make one whole.
• Thus, the answer is 5.

Ans: (d)

• To find the multiples of 5 between 20 and 80, we start with the first multiple, which is 20, and the last one, which is 80.
• The multiples of 5 in this range are: 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80.
• Counting these gives us a total of 13 multiples of 5.
• Thus, the correct answer is (d) 13.

Ans: (d)

• The number 86000 has the digit 8 in the ten-thousands place and the digit 6 in the thousands place.
• The place value of 8 is 80,000 and the place value of 6 is 6,000.
• Adding these place values gives 80,000 + 6,000 = 86,000.
• Thus, the sum of the place values of 8 and 6 in 86000 is 86000.

• Start with the initial amount in Sachin's account: ₹37,683.
• After withdrawing ₹13,435, the new balance is ₹37,683 - ₹13,435 = ₹24,248.
• Then, he deposits ₹1,829, resulting in a final balance of ₹24,248 + ₹1,829 = ₹26,077.
• Thus, the amount of money in Sachin’s account now is ₹26,077.

Ans: (d)

• To find the total number of saplings Anju planted, we need to multiply the number of saplings per row by the number of rows.
• So, we calculate: 24 saplings/row × 16 rows = 384 saplings.
• This means Anju planted a total of 384 saplings.
• Thus, the correct answer is (d) 384.

Ans: (b)

• On Monday, Tarun sold 1/5 of 250 kg, which is 50 kg (250 kg ÷ 5 = 50 kg).
• On Tuesday, he sold 1/10 of 250 kg, which is 25 kg (250 kg ÷ 10 = 25 kg).
• To find the total sold, add both amounts: 50 kg + 25 kg = 75 kg.
• Thus, the total quantity of flour he sold on both days is 75 kg.

Ans: (b)

• To find the distance Manya walked each day, we need to divide the total distance by the number of days in July.
• July has 31 days, so we calculate: 465 km ÷ 31 days = 15 km per day.
• This means Manya walked the same distance of 15 km every day throughout the month.
• Thus, the correct answer is 15 km.

Ans: (a)

• To find the total earnings, we need to multiply the number of fans sold by the cost of each fan.
• The shopkeeper sold 85 fans and each fan costs ₹480.
• So, the total earnings = 85 fans × ₹480 = ₹40,800.
• Thus, the shopkeeper earned ₹40,800 in that month.

Ans: (a)

• First, calculate the total number of guests currently in the restaurant by adding the number of adults and children: 1205 + 1820 = 3025.
• Next, subtract the current number of guests from the total capacity: 5200 - 3025 = 2175.
• This means the restaurant can accommodate 2175 more guests.
• Thus, the correct answer is (a) 2175.

Ans: (b)

• To find the cost of 1 banana, first calculate the total number of bananas in 4 dozen. Since 1 dozen equals 12, 4 dozen equals 4 x 12 = 48 bananas.
• Next, divide the total cost of the bananas by the number of bananas: ₹96 ÷ 48 = ₹2.
• Thus, the cost of 1 banana is ₹2.

Ans: (d)

• To find the total cost, we calculate the price for each item Harshi bought:
• 2 cupcakes cost: 2 x ₹50 = ₹100
• 5 patties cost: 5 x ₹25 = ₹125
• 3 cold drinks cost: 3 x ₹50 = ₹150
• 3 muffins cost: 3 x ₹30 = ₹90
• Now, add all these amounts together: ₹100 + ₹125 + ₹150 + ₹90 = ₹465
• Thus, the total amount Harshi has to pay is ₹465.

• In a rectangle, opposite sides are equal, which means it can have two pairs of equal sides, not all different.
• An isosceles triangle has at least two equal sides, while an equilateral triangle has all three sides equal.
• A square is a special type of rectangle where all four sides are equal.
• Thus, the statement about a rectangle having all sides different is incorrect.

Ans: (d)
The jewellery weighs 2 g 50mg  + 12 g 675 mg = 14 g 725 mg  
Now, 14 g 725 mg – 8 g of gold = 6 g 725 mg  
She needs to pay for 6 g 725 mg of gold. 

Ans: (a)
Four people in the elevator  weigh 75 kg + 65 kg + 40 kg + 33 kg = 213  kg  
The elevator can carry a maximum of 280  kg  
Therefore, fifth person can weigh (280 –  213) kg = 67 kg and less than 67 kg  
A person weighing 70 kg cannot be  allowed into the elevator. 

Ans: (d)
Time taken by Garima to  make 1 plane = 3 minutes  
Time taken by Garima to make 100 planes  = 3 × 100 minutes = 300 minutes  =  300/60  = 5 hours.  
So, 5 hours after 2: 30 p.m. = 7: 30 p.m.  
But she takes the break of 35 minutes, so  we add these 35 minutes to 7: 30 p.m.  
Thus, 7: 30 p.m. + 35 minutes = 8: 05 p.m. 

Ans: (a)
She has 30 notes of ₹ 5  = ₹ 5 × 30 = 150  and 9 notes of ₹ 10 = ₹ 10 × 9 = ₹ 90  
So, the total is ₹ 150 + ₹ 90 = ₹ 240  
Now, the difference between the number  of ₹ 5 and ₹ 10 notes = 30 – 9 = 21  
So, she has 21 more ₹ 5 notes than ₹ 10.
