• B. 22 : 21
• C. 32 : 21

Answer 1

The correct option is C

32 : 21

The earnings of Ram for 7days = Rs . 80

The earnings of Ram for 1 day

$=\frac{80}{7}$

The earnings of Hari for 12 days = Rs . 90

The earnings of Hari for 1 day

$=\frac{90}{12}=\frac{15}{2}$

The ratio of their earnings

$=\frac{80}{7}\times \frac{2}{15}=\frac{32}{21}=32:21$
