If a water tank has 500-litre water, then how many maximum pots, of equal capacity of 250 ml, can be filled from the water tank?

Detailed Solution for Test: Unit Conversions - Question 5

Given:

The capacity of water tank = 500 litre

The capacity of a pot = 250 ml

Formula used:

1 litre = 1000 ml

Calculation:

The capacity of water tank = 500 litre

= 500 × 1000 = 500000 ml

Capacity of a pot = 250 ml

Required pots = 500000/250 = 2000

∴ Maximum 2000 pots can be filled from the water tank.

Test: Unit Conversions - Question 6

Vaishnavi has only Rs. 5, Rs. 10 and Rs. 20 coins in her collection. The number of Rs. 5 coins is thrice that of Rs. 10 coins and number of Rs. 20 coins is half of that of Rs. 10 coins. If the collection contains 7 number of Rs. 20 coins, then how much amount she will have in total?

Detailed Solution for Test: Unit Conversions - Question 6

Given:

There are three types of coins Rs. 5, Rs. 10 and Rs. 20 coins

Total number of Rs. 20 coins = 7

Calculation:

Total number of Rs. 20 coins = 7

∴ The total amount of Rs. 20 coins = 7 × 20 = Rs. 140

The number of Rs. 20 coins are half of that of Rs. 10 coins.

Total number of Rs. 10 coins = 7 × 2 = 14

∴ Total amount of Rs. 10 coins = 14 × 10 = Rs. 140

The number of Rs. 5 coins is thrice that of Rs. 10 coins.

Total number of Rs. 5 coins = 14 × 3 = 42

∴ Total amount of Rs. 5 coins = 42 × 5 = Rs. 210

Total amount of the Rs. 5, Rs. 10 and Rs. 20 coins = (210 + 140 + 140) = Rs. 490

∴​ Vaishnavi will have in total of Rs. 490.

Test: Unit Conversions - Question 7

Rae and Reena have arranged the bricks horizontally one above the other. If the length, width and height of each brick are 6 inches, 3 inches, and 3 inches, respectively then how many rows of the bricks will be required to create a 3.5 meter wall?

Detailed Solution for Test: Unit Conversions - Question 7

Given:

Lenght of a brick = 6 inches

Width of a brick = 3 inches

Height of a brick = 3 inches

Height of the wall = 3.5 meters

Calculation:

Height of a brick = 3 inches

We know, 1 meter = 39.3701 inches ≈ 39.4 inches

Height of the wall = 3.5 meters = 3.5 × 39.4 = 137.9 inches

Total rows of bricks required to create the wall = 137.9/3 = 45.97 ≈ 46

∴ A total of 46 rows of bricks will be required to create a 3.5-meter wall.

Jalebi brought = 3 kg 250 g

Rasgulla brought = 4 kg

Box capacity = 750 g

Formula used:

1 kg = 1000 g

Calculation:

Total amount of Laddu = 2 kg 500 g = (2 × 1000) + 500 = 2500 g

Total amount of Jalebi = 3 kg 250 g = (3 × 1000) + 250 = 3250 g

Total amount of Rasgulla = 4 kg = (4 × 1000) = 4000 g

Total amount = (2500 + 3250 + 4000) = 9750 g

Maximum capacity of a box = 750 g

Total box required = 9750/750 = 13

∴ Total 13 boxes required to pack all the items.

Sunil travel 250km from A to B.

Total time he took = 9 Hrs

Rates of hiring car are:

⇒ 8hr up to 80Km = Rs.800

Per extra Hour = Rs.100

Per extra Km = Rs.10

Sunil' s total distance is 250Km.

For first 80km he pay = Rs.800----(i)

Left (250 - 80 = 170Km)

He pay according to Km = 170 × 10 = 1700---(ii)

But, He use extra 1hr for this he pay = Rs.100-----(iii)

Total money he pay = Rs.800 + Rs.1700 + Rs.100 = Rs.2600
