Q:

The present average age of a family of five members is 26 years. If the present age of the youngest member in the family is ten years, then what was the average age of the family at the time of the birth of the youngest member ? (Assume no death occurred in the family since the birth of the youngest)

A) 19 years B) 16 years
C) 18 years D) 20 years
 
Answer & Explanation Answer: D) 20 years

Explanation:

Present total age of the members = 26(5) = 130 years.

 

Present age of the youngest member = 10 years

 

Present total age of the remaining four members = 130 -10 = 120 years

 

Their average age at the time of the birth of the youngest member = 120-4×104 = 30 - 10 = 20 years.

From c also, profit after 3 years = Rs. (2750 x 3) = Rs. 8250.

Q:

Which veda deals with medicine?

A) Atharva Veda B) Yajur Veda
C) Sama Veda D) Rig Veda
 
Answer & Explanation Answer: A) Atharva Veda

Explanation:

The Vedas are considered the earliest literary record of Indo-Aryan civilization. It is the most sacred scriptures of India.

 

There are four Vedas in Hinduism. They are:

1. The Rig Veda,

2. Sama Veda,

3. Yajur Veda and

4. Atharva Veda.


Most ailments, both physical and mental, were attributed to malevolent spirits and cures consisted of rituals, charms, mantras, medicines and surgical intervention.

The hymns in the Atharva Veda, the last of the four Vedas, and largely composed after the Aryans were well settled in the sub-continent, indicate that indigenous non-Aryan healing practices had influenced the Vedic Aryan healers.
