The average age of four friends is 22 years. A fifth friend aged 27 joins them. What is the new average age?

Explanation / وضاحت

Correct answer: C — 23 years

پہلے چار دوستوں کی عمروں کا مجموعہ نکالیں۔ پھر پانچویں دوست کی عمر جمع کرکے پانچ پر تقسیم کریں۔

4 × 22 = 88
88 + 27 = 115
115 ÷ 5 = 23

نیا اوسط ۲۳ سال ہے۔

Source: Original worked example; calculation: (4 × 22 + 27) ÷ 5 = 23.
