six days.​

Answer 1

Step-by-step explanation:

But we want the least 4 digit number, which is exactly divisible by 18, 24 and 36. Smallest 4 digit number = 1000. Next higher quotient is 14. Hence, the required number is 1008, which is exactly divisible by 18, 24 and 36.

Using unitary method.The cost of 1 pencil is 140÷35=4

Cost of 16 pencil=16×4=60₹
