DECIMALS
Integrated with Business Studies

In business, decimals are frequently used to do math (or calculation).
For example, to calculate 10% profit on a given amount, the amount is
simply multiplied by 0.1. The use of decimals makes the calculations
easier and faster. The other fields like banking, finance and marketing
also use decimals for calculations.
Can you calculate a profit of 10% on ` 2,50,000 by simply multiplying
it by 0.1?

SET THEORY
Integrated with Social Sciences
Form a set of all prime ministers of independent India. How many of them became prime minister
twice? Does A. P. J. Abdul Kalam belong to any of these two sets and why?

RATIO, PROPORTION AND UNITARY METHOD
Integrated with Medical Sciences

Doctors and nurses often use the concept of ratio and proportion in dosage
calculation. For example, suppose a nurse has a medication with a dosage
strength of 100 mg per 1 mL, and a doctor orders a dosage of 50 mg.
Here, the concept of ratio and proportion helps the nurse to determine
how many mL to administer as,
100 mg : 1 mL : : 50 mg : x mL

Using the above proportion, calculate how many mL should the nurse administer.
