let x be total no of students studying Japanese

let y -> French

Stmt II is telling us

that .04y = .10x

x/y = 5/2

2x = 5y

This means y<x i.e no of students studying french is lesser than numbe of students studying Japanese

The question is saying Japanese >= 100. Imo I dont see this info being used anywhere since the question is not asking us to find numbers but just find out if Japanese more than French which u can from the ratios.

Don't we need at least 100 students to check statement 1
Statement 1:
16 study both French and Japanese
if # of French = y
then 4%of y = 16 study both
==>y = 400
since number of Japanese >100
So statement 1 is insufficient ?
Did I missed any thing ?

Question says AT LEAST 100 students study Japanese, this number could be 401, because stmt 1 doesn't utilize the number of students studying Japanese at all, we can't compare.

Am I correct or am I missing something?
