Question

3. Ram has 3 times as many 2 coins as he has 5 coins. If he has in all a sum of 77, how many coins
of 2 does he have?




4. The sum of three consecutive numbers is 156. Find the number which is a multiple of 13 out of these
numbers​

Answer 1

Answer:

3)21 4)52

Step-by-step explanation:

3) if ram has 3x as much 2 coins as he has 5 coins, then the ratio of the money would be 3x2:5x1, which is 6:5. 6+5 is 11, and 77/11=7, so the total amount of money he has is 7x6=42 in 2 coins and 7x5=35 in 5 coins.  We want to know the number of 2 coins he has, so 42/2=21

4) the 3 consecutive number would be 156/3-1, 156/3 and 156/3+1. so the numbers are 51, 52 and 53. 52 is a multiple of 13

hope this helped :)
