1 oothecae produces 14-16 eggs Then 10 oothecae will produce 140-160 eggs

One Ootheca Contain 14-16 Eggs 10 Ootheca 140-160 Eggs

1 oothecae contains 16 eggs 8 in each row And this eggs are fertilised because oothecae is the covering of fertilised eggs but sometime oothecae are dropped early then hacking of eggs oothecae are found in the abdomen of cockroach

So 1 oothecae contains 16 eggs SO 10 OOTHECAE CONTAINS 160 EGGS

It is mentioned in NCERT that female cockroach produce 9 to 8 oothecae and in each ootheca they lays 14 to 16 eggs it means in 1 oothecae they lays 14 or 16 eggs SO in 10 oothecae they lay 15 to 17 eggs

Sorry by mistake I had wrote last line it would be 140-160
