Answer the following questions. Each question carries 2 marks. (8 marks)
a) Rahul buys 3 types of balls. Type 1 costs 10 each, Type 2 costs 8 each, and
Type 3 costs 25 each. What is the least number balls of each type he should buy so
that he spends an equal amount on each type of ball?​

Answer 1

Answer:

5850

Explanation:

LCM= 10,25,78

10= 2×5

75= 2×3×13

25= 5×5

LCM =2×5×2×3×13×5×5=1959

thus,we would buy,

1950/10=195 balls costing 10 each

1950/78=25 balls costing 78 each

1950/25=78 balls costing 25 each

In that way he would spend 1950 in buying each type of balls

his total expenditure would be

1950+1950+1950=

5850
