The value of log 2 + log 5 (base 10) is:
सही उत्तर: क) 1
log 2 + log 5 = log (2 × 5) = log 10 = 1. The sum of logs is the log of the product, not log 7.

If 2^(x + 1) = 32, then x equals:
सही उत्तर: ग) 4
32 = 2⁵, so x + 1 = 5 and x = 4. Choosing 5 forgets to subtract the 1 in the exponent.

If x + y = 10 and x − y = 4, then the values of x and y are:
सही उत्तर: घ) x = 7, y = 3
Adding gives 2x = 14, so x = 7, and then y = 3. Check: 7 − 3 = 4. The pair x = 3, y = 7 gives x − y = −4.

The sum of the roots of the quadratic equation 2x² − 7x + 3 = 0 is:
सही उत्तर: घ) 7/2
For ax² + bx + c = 0, sum of roots = −b/a = 7/2. 3/2 is c/a, which is the product of the roots.

The roots of the equation x² − 5x + 6 = 0 are:
सही उत्तर: क) 2 and 3
x² − 5x + 6 = (x − 2)(x − 3) = 0, so x = 2 or 3. −2 and −3 would be the roots of x² + 5x + 6 = 0.

What principal will earn Rs 1,800 simple interest in 3 years at 12% per annum?
सही उत्तर: ख) Rs 5,000
P = (I × 100)/(T × R) = (1800 × 100)/(3 × 12) = Rs 5,000. Always divide by the product of time and rate.

At simple interest, a sum of money doubles itself in 8 years. The rate of interest per annum is:
सही उत्तर: ग) 12.5%
Doubling means interest = principal, so R = 100 / 8 = 12.5% per annum. Rule: rate × time = 100 when a sum doubles at simple interest.

An article is sold for Rs 450 at a loss of 10%. Its cost price is:
सही उत्तर: ग) Rs 500
SP = 90% of CP, so CP = 450 / 0.9 = Rs 500. Rs 495 wrongly adds 10% of the SP to the SP.

Two successive discounts of 20% and 10% are equivalent to a single discount of:
सही उत्तर: घ) 28%
Remaining price = 0.80 × 0.90 = 0.72 of the marked price, so the single discount is 28%. Simply adding gives 30%, which is wrong because the second discount is on a reduced price.

The marked price of a jacket is Rs 2,000. A 15% discount is allowed and then 13% VAT is added. The price the customer pays is:
सही उत्तर: क) Rs 1,921
Price after discount = 2000 × 0.85 = 1700; with VAT = 1700 × 1.13 = Rs 1,921. Rs 1,700 forgets the VAT, and Rs 2,260 forgets the discount.
