Question

The image shows the composition of concrete. A heap of concrete weighs 6,600
kilogram. A quantity of cement, sand and gravel are added to this heap in the same ratio
as shown in the image and the weight of the heap becomes 7,050 kilogram. How many
more kilograms of cement were added to the new heap?​

Answer 1

Answer:

150 kg of cement

Step-by-step explanation:

Since all the three things are added in the same ratio, therefore cement is one third of the whole amount that is added.

The added amount is 7050-6600 = 450

Now, one thirds of 450 is 450/3 = 150

Thus, the added cement = 150 kg
