Solution

(a) Correct statement of equation: 1 Mark each
(b) Framing of equation: 1 Mark
Solution: 1 Mark

(a) i) When a number is multiplied with 7 and 4 is added to their product, we get 46 as the final result.

ii) When a number is multiplied with 5, 4 is added to their product and their final sum is divided by 6, the result which we get is 13.

(b) Let Raju's age be x.
Raju's father's age = 3x+5=44

3x+5=44

3x=445=39

x=393

x=13 years
Raju's age is 13 years.
