Hi ,
We know that ,
______________________________
If a : b = c : d , we write a : b : : c : d and
we say that a , b , c , d are in proportion.
a and d are known as extrems , while
b and c are known as means .
If a : b : : c : d then
Product of extrems = product of means
ad = bc
_________________________________
According to the problem given ,
13 : 30 : : 41 : x
13 × x = 30 × 41
x = ( 30 × 41 ) / 13
x = 1230 / 13
x = 94.615
I hope this helps you.
