Question

In a certain deck of cards, each card has a positive integer written on it. In a multiplication game, a child draws a card and multiplies the integer on the card by the next larger integer. If each possible product is between 15 and 200, then the least and greatest integers on the cards could beA. 3 & 15B. 3 & 20C. 4 & 13D. 4 & 14E. 5 & 12

Answer 1

The answer is: C. 4 & 13.

Step-by-step explanation:

Using the given information:

• The lower limit is 15.

• The upper limit is 200.

• Each card number is multiplied by its next larger integer.

• The range is between 15 and 200, not exactly between 15 and 200.

For A:

• 3*4 = 12 doesn't meet the condition for the lower limit.

For B:

• 15*16 = 240 doesn't meet the condition for the upper limit.

For C:

• 4*5 = 15 meets the condition for the lower limit.
• 13*14 = 182 meets the condition for the upper limit.

For D:

• 5*6= 20 doesn't meet the condition for the lower limit.
