II. Mr. Roy sold a cupboard to Mohan for RO 60 and earned a profit of RO 10. Mohan spent RO 27 to polish and repair the cupboard. He then sold it to Gopi at a profit of RO 8. After using the cupboard for a year , Gopi sold it to a furniture dealer for RO 90. Did Gopi make a profit or a loss in the deal? *

Gopi made a loss in the deal

Step-by-step explanation:

To solve this question, we'll analyse each statement in the question one after the other.

From Roy to Mohan,

The profit of goes to Roy

Mohan spent on polish and repairs.

So, the cost price of the cupboard becomes

He sells at a profit of . to Gopi

So, the selling price is:

At this stage, the cost price of the cupboard to Gopi is:

and

Profit is calculated as:

Because; the profit is negative, then it is a loss.

Gopi made a loss in the deal

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
