a shopkeeper marks his goods at 30 percent
above the cost price and then gives a discount
of 10 percent. find his gain percent.

Step-by-step explanation:

Let the cost price be = $ 100

Increased price = 100 * 30/100   = $30

Market price = 100 +30 = $130

Discount amount = 10% of 130 = 10/100 * 130 = $ 13

Price after discount = 130 - 13 = $ 117

Gain = 117 -  100 = 17

Gain = 17%

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
