Answer:
There are two ways to find the answer. Both ways are given below :-
(i) 2/3 of cattle are diary cows
=> 2/3 of 7/16
=> 2/3 × 7/16
=> 7/24
7/24 of animals are diary cows
=> 7/24 of 192
=> 7/24 × 192
=> 7 × ( 192 ÷ 24 )
=> 7 × 8
=> 56
OR
(ii) 7/16 of animals are cattle
=> 7/16 of 192
=> 7/16 × 192
=> 7 × ( 192 ÷ 16 )
=> 7 × 12
=> 84
and 2/3 of cattle are diary cows
=> 2/3 of 84
=> 2/3 × 84
=> 2 × ( 84 ÷ 3 )
=> 2 × 28
=> 56
Hence, 56 animals are diary cows .
