After a 10% discount, 90% remains; after another 20%, 80% of that remains.
The final price is 72%, so the total discount is 28%.

Let cost be 100; marked price is 125 and sale price is 90% of 125 = 112.5.
The profit is 12.5 on a cost of 100.

For inverse variation, xy is constant.
Since 12 × 4 = 48, x = 48/6 = 8.

Two centimeters represent 100,000 centimeters in reality.
Since 100,000 cm = 1 km, the answer is 1 kilometer.

The difference of ratio parts is 5, corresponding to 35.
One part is 7, so the larger number is 9 × 7 = 63.

Make the common term b equal in both ratios.
Multiplying 4:7 by 2 gives 8:14, so a:b:c = 8:14:15.

Five parts equal Rs. 50,000, so one part is Rs. 10,000.
Expenditure is four parts, leaving one part as saving.

The cost per pen is 150 ÷ 5 = Rs. 30.
Eight pens cost 8 × 30 = Rs. 240.

Workers and time are inversely proportional for fixed work.
Thus, 12 × 15 = 20 × days, giving 9 days.

The sum is 12 + 18 + 20 + 30 = 80.
Dividing by 4 gives an average of 20.

Total equals average multiplied by the number of values.
Thus, 24 × 5 = 120.

The original total is 8 × 15 = 120.
After removing 22, the total is 98, and 98 ÷ 7 = 14.
