• If x = 0 the point lies on the y-axis.
• If y = 0 the point lies on the x-axis.
• If both x and y are non-zero, the point lies in one of the four quadrants.
• Here, the point is (0, -7), where x = 0 and y = - 7.
• → It lies exactly on the y-axis, not in any quadrant

• Let's evaluate the expression:
• 5+51 =56
• 56+(-3)=56-3 =53
• 53+7=60
• 60 + (-5.1) =60 - 5.1 = 54.9

• Let's use the simple interest formula:
• Simple Interest (SI) = (Principal x Rate x Time)/100
• Given: Principal (P) = Rs 450
• SI = Rs 81
• Rate (R) = 4.5% per annum
• We need to find Time (T). Rearranging the formula
• 81 = (450 * 4.5 *T) / 100
• Multiply both sides by 100:
• 8100 = 450 * 4.5 * T
• 8100 = 2025 * T
• Divide both sides by 2025:
• T = 8100/2025
• T = 4
• The correct answer is: (C) 4 years

• Work done by A + B in 1 day = 1/12
• Work done by A+B+C in 1 day = 1/8
• So, C's 1 day work = (1/8) - (1/12) = (3 - 2) / 24 = 1/24
• →C alone can finish the job in 24 days.

• To find the number of working keyboards, we need to subtract the number of non-working keyboards from the total.
• Number of non-working keyboards = 1/5 x 3,000 = 600
• Number of working keyboards = Total keyboards - Non-working keyboards

=3,000-600

= 2,400

• The correct answer is: (D) 2400

• Consecutive integers are numbers that follow each other in order, e.g., n, n+1, n+2
• The sum of three Consecutive integers is written as
• n + (n+1) + (n+2) = 3n + 3
• n + (n+1) + (n+2) = 33 \implies 3n + 3 = 33 \implies 3n = 30 \implies n = 10
