Answer of this question is OPTION 4
Explanation:
(280 x n)/100 + (550 x 18)/100 = 143.8
280 x n + 9900 = 143.8 x 100
280 x n + 9900 = 14380
280 x n = 14380 – 9900
n = 4480/280
n = 16
Hence answer is Option (4) 160Modal content

Answer will be Option (4) as
(280 x ?)/100 + (550 x 18)/100 = 143.8
280 x ? + 9900 = 143.8 x 100
280 x ? + 9900 = 14380
280 x ? = 14380 – 9900
? = 4480/280
? = 16
Hence answer is Option (4) i.e., 16
