Pakistan MCQs

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

The amount is 8,000 × 1.05² = Rs. 8,820.
Subtracting the principal gives compound interest of Rs. 820.

Six consecutive integers centered at 17.5 are 15 through 20.
Therefore, the smallest is 15.

For two years, the difference is P(r/100)².
So 10,000 × 0.1² = Rs. 100.

The average of 1 through n is (n + 1)/2.
Setting (n + 1)/2 = 20 gives n = 39.

Doubling means interest equal to the principal is earned in 8 years.
Tripling requires interest equal to twice the principal, so it takes 16 years.

The difference between C and A is 2 ratio parts, equal to Rs. 600.
One part is Rs. 300, so 12 parts total Rs. 3,600.

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.

The original total age is 4 × 25 = 100 years.
The new total is 5 × 27 = 135, so the new age is 35.

One hundred fifty percent equals 1.5.
Multiplying 80 by 1.5 gives 120.

Since 12.5% = 1/8, one eighth of the number is 25.
The whole number is 25 × 8 = 200.
