Answer 2

Given

• a + b + c / 3 = 24
• a = 18
• b = 19

To find

• c

Solution

• 18 + 19 + c / 3 = 24
• 37 + c / 3 = 24
• 37 + c = 24 × 3
• 37 + c = 72
• c = 72 - 37
• c = 35

∴ Value of third number c = 35

Verification

• a + b + c / 3 = 24
• 18 + 19 + 35 / 3 = 24
• 72 / 3 = 24
• 24 = 24
• L.H.S = R.H.S
