Question

. A money box contains one-rupee and two-rupee coins in the ratio 5:6. If the total
value of the coins in the money box is * 85, find the number of two-rupee coins.​

Answer 1

Answer:

30

Step-by-step explanation:

given  1 re coin 2 re coin are in the ratio 5: 6

LET  no of 1 re coins be  5x

let    no of  2 re coins be  6x

so total values     1[5x] + 2[6x] = 85

                              5x + 12x    = 85

                                         17x    = 85

                                               x = 5  

no of  2 re coins be  6x  = 30

Answer 2

let the number of 1 ruppee coins be 5x

and

let the number of two ruppee coins be 6x

ATQ ,

1 (5x)+2 (6x)=85

5x + 12x = 85

17x = 85

x = 85 /17

x =5

number of two ruppee coins= 6* 5

=30

THE NUMBER OF TWO RUPPEE COINS IS 30
