Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 568 : 499.
Given that
The sweets manufactured by factories P. Q and R together in the year 1998 = 178 + 240 + 150 = 568
The sweets manufactured by factories S.T and U together in the same year 1998 = 130 + 177 + 192 = 499
Hence, the required ratio is 568 : 499
