The given equation involves adding two negative numbers. When we add two negative numbers, the result is always negative. In this case, the sum of -56 and -73 is -129.

A cake weighing 3 kg can be divided into 12 pieces of 250g each. This is because 3 kg is equal to 3000g, and when divided by 250g, it gives a quotient of 12. Therefore, 12 pieces of 250g can be cut from the cake.

The given statement is true because multiplying two negative numbers always results in a positive number. Therefore, (-5) multiplied by (-7) is the same as (-7) multiplied by (-5), both of which give a positive product.

The boy starts on the third stair and goes up by five more stairs, which would place him on the eighth stair. However, he then comes down by three stairs, which means he moves three stairs down from the eighth stair. Therefore, he is standing on the fifth stair now.

The pattern in the given sequence is that each number is decreasing by 5. Starting from 15, each subsequent number is obtained by subtracting 5 from the previous number. Therefore, the missing number after 0 would be obtained by subtracting 5 from 0, resulting in -5.

The given answer is correct because by observing the number line, we can see that B is not greater than A. In fact, A is greater than B. Therefore, the statement "B is greater than A" is not true.

The given expression is the sum of two negative numbers: -56 and -73. When adding negative numbers, the result is also a negative number. In this case, the sum of -56 and -73 is -129.

The given equation is multiplying 2.4 by 1000. When multiplying a decimal number by 1000, we move the decimal point three places to the right. Therefore, the decimal point in 2.4 will be moved three places to the right, resulting in the number 2400.

The correct answer is 8.08. This is because the given amount is 8 rupees and 8 paise. To express this in decimal form, we place the paise value after the decimal point. Therefore, the decimal expression for 8 rupees 8 paise is 8.08.

The green grocer had a profit of Rs 47 on Monday, a loss of Rs 12 on Tuesday, and a loss of Rs 8 on Wednesday. To find the net profit or loss, we need to add up all the profits and subtract all the losses. Rs 47 profit - Rs 12 loss - Rs 8 loss = Rs 27 profit. Therefore, the correct answer is Rs 27 profit.

Harmeet purchased 3kg of potatoes at the rate of Rs12 per kg. Therefore, the total cost of the potatoes is 3 * 12 = Rs36. He gave Rs2000 to the shopkeeper. To find out how much money he should get back, we need to subtract the cost of the potatoes from the amount he gave. So, 2000 - 36 = Rs1964.

A regular hexagon has six equal sides. Given that each side is 3.5cm long, we can find the perimeter by multiplying the length of one side by 6. Therefore, the perimeter of the given polygon is 3.5cm * 6 = 21cm.
