Explanation

3(x - 4) + 2 = 2x + 9

3x - 12 + 2 = 2x + 9

3x - 10 = 2x + 9

3x - 2x = 9 + 10

x = 19

Explanation

Total = 120

Neither = 20

At least one software = 120 - 20 = 100

Formula:

Spreadsheet + Presentation - Both = At least one

68 + 52 - Both = 100

120 - Both = 100

Both = 20

Explanation

Let smallest angle = x

Then:

Second angle = 2x

Third angle = x + 30

Total in triangle = 180

x + 2x + x + 30 = 180

4x + 30 = 180

4x = 150

x = 37.5

Largest angle = 2x = 2 x 37.5 = 75

Answer = 75 degrees

Explanation

Let original allowance = 100

1. Increased by 20%

100 + 20% of 100 = 120

2. Reduced by 10% of the increased amount

10% of 120 = 12

120 - 12 = 108

Final = 108

Overall change = +8% from original.

i.e. a net increase of 8%.

6 clerks × 8 hours = 48 clerk-hours

48 clerk-hours = 720 applications

1 clerk-hour = 720 / 48 = 15 applications

Now:

5 clerks × 6 hours = 30 clerk-hours

30 × 15 = 450 applications

Ratio = Stationery : Printing = 3 : 5

Difference = 5 - 3 = 2 parts

2 parts = Rs 48,000

1 part = Rs 24,000

Total allocation = 3 + 5 = 8 parts

8 × 24,000 = Rs 192,000

Explanation

To get a 5-hour average of 20, you need a total of 100 cases.

Cases in first 4 hours:

18 + 22 + 20 + 16 = 76

Cases needed in 5th hour:

100 - 76 = 24
