Answer» Amount SPENT by Ramesh on rent and utilities = 60/100 × x = 0.6x ⇒ Remaining amount LEFT = x – 0.6x = 0.4x ⇒ Amount spent by Ramesh on food = 80/100 × 0.4x = 0.32x ⇒ Remaining amount left = 0.4x – 0.32x = 0.08x ⇒ Remaining amount after buying a shirt = Savings = 0.08x – 360 ⇒ Amount spent by SURESH on rent and utilities = 75/100 × y = 0.75y ⇒ Remaining amount left = y – 0.75y = 0.25y ⇒ Amount spent by Suresh on food = 90/100 × 0.25y = 0.225y ⇒ Remaining amount left = 0.25y – 0.225y = 0.025y ⇒ Remaining amount after buying a hat = Savings = 0.025y – 75 Given that the saving of Ramesh is 100% more than that of Suresh i.e. twice that of Suresh ⇒ 0.08x – 360 = 2 × (0.025y – 75) ⇒ 0.08x – 0.05y = 210---- (1) ⇒ Total salary received = x + y = 27000---- (2) ∴ SOLVING we get x = 12000 and y = 15000 |
