The expansion of (a + b)² is:
सही उत्तर: ग) a² + 2ab + b²
(a + b)² = (a + b)(a + b) = a² + 2ab + b². A common mistake is to omit the middle term 2ab.

The degree of the polynomial 4x³ − 2x⁵ + 7x − 1 is:
सही उत्तर: ग) 5
The degree is the highest power of the variable with a non-zero coefficient, here x⁵. The order in which terms are written does not matter.

A polynomial of degree 2 is called a:
सही उत्तर: घ) Quadratic polynomial
The degree is the highest power of the variable; degree 2 means quadratic, such as ax² + bx + c. Degree 1 is linear and degree 3 is cubic.

VAT (Value Added Tax) in Nepal is levied at the rate of:
सही उत्तर: क) 13%

Discount is always given on the:
सही उत्तर: ख) Marked price
Discount = Marked price − Selling price, and discount % is calculated on the marked price. Profit and loss % are calculated on the cost price.

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.
