Explanation

Let's break this down step by step:

1. Let the man's monthly income be x.
2. He spends Rs. 3500 per month, which means his savings are x - 3500.
3. He saves 12 ½% of his income, which can be written as a decimal: 0.125x.
4. Since his savings are equal to his income minus his expenses, we can set up the equation: 0.125x = x - 3500.
5. Simplify the equation: 0.125x = x - 3500 --> 0.125x - x = -3500 --> -0.875x = -3500.
6. Divide both sides by -0.875: x = 3500 / 0.875 --> x = 4000.

So, the man's monthly income is Rs. 4000.

Explanation

Multiple type questions have increasing objectivity of marking.

They offer clear and defined answer choices, making it easier for graders to determine the correctness of responses objectively.

Explanation

The correct option is: This is the only one of his poems that is worth reading.

In this sentence, the verb "is" agrees with the singular noun "one."

The phrase "of his poems" modifies "one," but it doesn't change the singular nature of the subject.

Therefore, the singular verb form "is" is correct.

Explanation

Let's break this down step by step:

1. Let Ali's current age be A and Zia's current age be Z.
2. Since Ali is younger than Zia by 10 years, we can write an equation: A = Z - 10
3. We know that 5 years back, their ages were in the ratio 1:2. So, we can set up another equation based on their ages 5 years back: (A-5)/(Z-5) = 1/2
4. Cross-multiply and simplify the equation: 2A - 10 = Z - 5
5. Substitute the expression for A from step 2 into the equation in step 4: 2(Z-10) - 10 = Z - 5
6. Simplify and solve for Z: 2Z - 20 - 10 = Z - 5 --> Z = 25

So, Zia is currently 25 years old.
