  2. BOption (b)

    87

  3. COption (c)

    79

  4. DOption (d)

    82

View answer & explanation

Correct answer

Answer: (d)D.

82

Why this answer is correct

Shortcut Trick

For two supplementary angles, their total sum is always 180°.

Smaller angle = (Sum − Difference) ÷ 2

Smaller angle = (180° − 16°) ÷ 2

Smaller angle = 164° ÷ 2 = 82°

∴ The correct answer is 82°.

Alternate Method

  x x + 16° A B C O Straight Angle = 180°

Given:

The two angles are supplementary.

The larger angle is 16° more than the smaller angle.

Concept Used:

The sum of adjacent angles on a straight line (supplementary angles) is exactly 180°.

Calculation:

⇒ Let the smaller angle be x.

⇒ Then, the larger angle = x + 16°

⇒ Sum of supplementary angles = 180°

⇒ x + (x + 16°) = 180°

⇒ 2x + 16° = 180°

⇒ 2x = 180° − 16°

⇒ 2x = 164°

⇒ x = 164° ÷ 2

⇒ x = 82°

∴ The correct answer is 82°.

Additional Information

Supplementary Angles

Two angles are supplementary if their sum is exactly 180°. When placed adjacent to each other, they form a straight line or linear pair.

Complementary Angles

Two angles are complementary if their sum is exactly 90°, forming a right angle when combined.

Vertically Opposite Angles

When two straight lines intersect, the angles directly opposite to each other are equal. These pairs are independent of the supplementary linear pairs formed along each line.

  4. DOption (d)

    196

View answer & explanation

Correct answer

Answer: (b)B.

98

Why this answer is correct

Shortcut Trick

We know that, Product of two numbers = H.C.F. × L.C.M.

⇒ 245 × Second Number = 49 × 490

⇒ Second Number = (49 × 490) ÷ 245

⇒ Second Number = 490 ÷ 5 = 98

∴ The correct answer is 98.

Alternate Method

Given:

H.C.F. of two numbers = 49

L.C.M. of two numbers = 490

First number = 245

H.C.F. = 49 L.C.M. = 490 First Number = 245 Second Number = ? × × =

Formula Used:

First Number × Second Number = H.C.F. × L.C.M.

Calculations:

Let the second number be x.

⇒ 245 × x = 49 × 490

⇒ x = (49 × 490) ÷ 245

⇒ x = 490 ÷ (245 ÷ 49)

⇒ x = 490 ÷ 5

⇒ x = 98

∴ The correct answer is 98.

Additional Information

Product of Numbers Rule

For any two numbers a and b, the product of their H.C.F. and L.C.M. is always equal to the product of the numbers. Formula: a × b = H.C.F. × L.C.M.

Co-prime Numbers

Two numbers are said to be co-prime if their H.C.F. is 1. The L.C.M. of two co-prime numbers is always equal to their product.

Fractions H.C.F. & L.C.M.

H.C.F. of fractions = (H.C.F. of Numerators) ÷ (L.C.M. of Denominators). L.C.M. of fractions = (L.C.M. of Numerators) ÷ (H.C.F. of Denominators).

Question 8

GPSSB Tracer 2025• Full Test

Two pipes can fill a cistern, individually, in 99 min and 90 min, respectively. There is a pipe located at the bottom of the cistern to empty it. If all the three pipes are opened simultaneously, then the empty cistern gets filled in 50 min. How long will the pipe at the bottom of the tank take to empty the completely filled cistern if no other pipe is then open?

  1. AOption (a)

    841 min

  2. BOption (b)

    822 min

  3. COption (c)

    815 min

  4. DOption (d)

    825 min

View answer & explanation

Correct answer

Answer: (d)D.

825 min

Why this answer is correct

Shortcut Trick

Total capacity = LCM(99, 90, 50) = 4950 units.

Efficiency of A = 4950 ÷ 99 = 50 units/min.

Efficiency of B = 4950 ÷ 90 = 55 units/min.

Net efficiency of (A + B + C) = 4950 ÷ 50 = 99 units/min.

Efficiency of C = 99 − (50 + 55) = −6 units/min.

Time taken by C = 4950 ÷ 6 = 825 min.

∴ The correct answer is 825 min.

Alternate Method

Given:

Time taken by Pipe A to fill the cistern = 99 min

Time taken by Pipe B to fill the cistern = 90 min

Time taken by all three pipes (A + B + C) to fill the cistern = 50 min

Concept Used:

Total capacity = LCM of individual time taken

Efficiency = Total capacity ÷ Time taken

PipeTime (min)Total WorkEfficiency
A99495050
B9055
A + B + C5099

Calculation:

⇒ Let the efficiency of emptying Pipe C be Ec.

⇒ Total Efficiency = Efficiency of A + Efficiency of B + Efficiency of C

⇒ 99 = 50 + 55 + Ec

⇒ 99 = 105 + Ec

⇒ Ec = 99 − 105

⇒ Ec = −6 units/min

⇒ The negative sign indicates that Pipe C is an emptying pipe.

⇒ Time taken by Pipe C to empty the completely filled cistern = Total Work ÷ Efficiency of C

⇒ Time = 4950 ÷ 6

⇒ Time = 825 min

∴ The correct answer is 825 min.

Additional Information

Pipes & Cisterns Concept

If a pipe can fill a tank in x hours and another can empty it in y hours (where y > x), then the net part of the tank filled in 1 hour is (1/x) − (1/y).

Work & Wages

Wages are distributed in proportion to the total work done. If multiple people work for the exact same number of days, their wages are divided in the direct ratio of their efficiencies.

Alternate Working

When workers or pipes operate on alternate days or hours, calculate the combined work done in one complete cycle before multiplying it to approach the total required work without exceeding it.
