please mark me as a brainliest answer.
Bro ...... correct ans must be
30 .
because ,
ratio of 1 rs coin to 2rs coin
= 5 : 6 = 85 /-
so, one rupee coin and two rupee coins are different in amount .. first convert them into equal number.
so ,it would be
5 : 12 = 85/-
17 (of ratio) = 85/-
85÷17=5
so, there would be maximum in the 1 th part of ratio ..there will be 5one rupee coins
....
But we need for 2rupee coins in ratio form of 6 parts ..
speaking about 2 rupee coins ...
5 × 12
(no.of coin .. included in one part ). × (no. in ratio form )
= 60 ..
but it's for one rupee coins
hence ...
60÷2 = 30
so,ans is 30.
