Profit percentage is calculated on:
सही उत्तर: ख) Cost price
Profit % = (Profit/CP) × 100, so it is based on the cost price. Discount %, by contrast, is calculated on the marked price.

When interest is compounded half-yearly at R% per annum for T years, the amount is:
सही उत्तर: ग) P(1 + R/200)²ᵀ
Half-yearly compounding halves the rate per period (R/2%) and doubles the number of periods (2T). Hence A = P(1 + R/200)²ᵀ.

The value of an article after depreciation at R% per annum for T years is:
सही उत्तर: घ) P(1 − R/100)ᵀ
Depreciation reduces the value each year by R%, so the formula uses (1 − R/100). Population growth uses (1 + R/100) instead.

The compound amount on principal P at R% per annum for T years, compounded yearly, is:
सही उत्तर: क) P(1 + R/100)ᵀ
With yearly compounding, each year's amount becomes the next year's principal, so A = P(1 + R/100)ᵀ. P(1 + RT/100) is the simple-interest amount.

The formula for simple interest is:
सही उत्तर: क) I = PTR/100
Simple interest is principal × time × rate ÷ 100. P(1 + R/100)ᵀ gives the compound amount, not simple interest.

The set of elements that belong to A but not to B is denoted by:
सही उत्तर: ख) A − B
A − B (difference) contains the elements in A that are not in B. B − A is the opposite: elements of B not in A.

For two sets A and B, n(A ∪ B) is equal to:
सही उत्तर: ग) n(A) + n(B) − n(A ∩ B)
Adding n(A) and n(B) counts the common elements twice, so n(A ∩ B) is subtracted once. If the sets are disjoint, this reduces to n(A) + n(B).

-
Two sets that have no common element are called:
सही उत्तर: घ) Disjoint sets
Disjoint sets have an empty intersection, A ∩ B = ∅. Equivalent sets only have the same number of elements.

The set containing all elements under consideration in a problem is called the:
सही उत्तर: घ) Universal set
The universal set (U) contains all the elements under discussion; every other set in the problem is a subset of it. The power set is the set of all subsets of a given set.

-
If n(A) = 3, the number of subsets of set A is:
सही उत्तर: क) 8
A set with n elements has 2ⁿ subsets, so 2³ = 8. This count includes the empty set and A itself.
