Correct Answer - Option 3 : 800
Given:
Total salary = 3500
Calculation:
Ankita’s saving = 100 – 80
⇒ 20% of her salary
Benedict’s saving = 100 – 56
⇒ 44% of his salary
Christopher’s saving = 100 – 75
⇒ 25% of his salary
∴20/100 of her salary : 44/100 of his salary : 25/100 of his salary = 12 : 33 : 10
⇒ 20 × Ankita’s salary : 44 × Benedict’s salary : 25 × Christopher’s salary = 12 : 33 : 10
⇒20 × Ankita’s salary/44 × Benedict’s salary = 12/33
⇒Ankita’s salary : Benedict’s salary = 4 : 5
Similarly,
⇒44 × Benedict’s salary/25 × Christopher’s salary = 33/10
⇒Benedict’s salary : Christopher’s salary = 15 : 8
∴Ankita’s salary : Benedict’s salary = 4 : 5 ; Benedict’s salary : Christopher’s salary = 15 : 8
Taking Benedict as common we have,
Ankita : Benedict : Christopher = 12 : 15 : 8
The total salary of Ankita, Benedict, and Christopher = Rs. 3500
∴ salary of Benedict
⇒ 8/35 × 3500
⇒800
The salary of Benedict is 800.
