• Marks given to Meena

✪|| Solution ||✪

Marks given to Gokul = 6 × 4 + ( 15 - 6 ) × ( - 1 )

→ Marks given to Gokul = 24 + 9 × ( - 1 )

→ Marks given to Gokul = 24 + ( - 9 )

→ Marks given to Gokul = 15

Marks given to Meena = 12 × 4 + ( 15 - 12 ) × ( - 1 )

⇒ Marks given to Meena = 48 + 3 × ( - 1 )

⇒ Marks given to Meena = 48 + ( - 3 )

⇒ Marks given to Meena = 45
