Correct answer

Answer: (a)A.

7

Why this answer is correct

The correct answer is 7.

Key Points

Given:

The number of legs is 14 more than twice the number of heads.

Calculation:

Let the number of cows be x and the number of hens be y.

So the total number of heads = x + y

According to question

⇒4x+2y=2(x+y)+14   ⇒4x+2y=2x+2y+14   ⇒2x=14   ⇒x=7\Rightarrow4x+2y=2(x+y)+14\;\ \Rightarrow4x+2y=2x+2y+14\;\ \Rightarrow 2x=14\;\ \Rightarrow x=74x+2y=2(x+y)+14⇒4x+2y=2x+2y+14⇒2x=14⇒x=74�+2�=2(�+�)+14⇒4�+2�=2�+2�+14⇒2�=14⇒�=74�+2�=2(�+�)+14⇒4�+2�=2�+2�+14⇒2�=14⇒�=7

Hence, the number of cows is 7.

Question 123

  1. AOption (a)

  2. BOption (b)

  3. COption (c)

    60 years

  4. DOption (d)

    70 years

View answer & explanation

Correct answer

Answer: (a)A.

50 years

Why this answer is correct

Calculation:

Let the age of the father be x years and age of the elder son be y years.

Let the age of the younger son be z years.

From the first condition, we have

x=2y−−−(1)x=2y−−−(1)x=2y−−−(1)

From the second condition, we have

x+10=3(z+10)x+10=3(z+10)x+10=3(z+10)

⇒x=3z+20−−−(2)⇒x=3z+20−−−(2)⇒x=3z+20−−−(2)

From the third condition

y−z=15−−−(3)y−z=15−−−(3)y−z=15−−−(3)

From eq (2) and (3)

x=3y−25−−−(4)x=3y−25−−−(4)x=3y−25−−−(4)

From eq (1) and (4)

2y=3y−252y=3y−252y=3y−25

⇒y=25⇒y=25⇒y=25

∴ x=2y=2×25=50x=2y=2×25=50x=2y=2×25=50

Hence, father's age is 50 years.
