Option (a) is correct

As we know,

Average = (Sum of ages)/Members

So, 35 = sum/7

Sum = 245 years

If a member of 35 years is not induded, the sum of ages of 6 members will be = 245 – 35 = 210

Hence, the age eldest member = 6/21 x 210

= 60 years.

विकल्प (a) सही है

जैसा कि हम जानते हैं,

औसत = (Sum of ages)/Members

तो, 35 = sum/7

योग = 245 वर्ष

यदि 35 वर्ष के सदस्य को शामिल नहीं किया जाता है, तो 6 सदस्यों की आयु का योग

= 245 – 35

= 210 होगा

इसलिए, सबसे बड़े सदस्य की आयु

= 6/(21 )× 210

= 60 वर्ष।
