If perpendicular of a triangle is 20 and base is 12 then its area is?

A) 440 sq

B) 120 sq

C) 60 sq

D) 30 sq

Area=1/2 base*height

Area = 1/2 *12*20

area =120 sq

A plot is sold for Rs. 18,700 with a loss of 15%. At what price it should be sold to get profit of 15%?

A) 25300

B) 22300

C) 24300

D) 21300

Given that: S.P= 18700 , Loss= 15%

CP = ( SP * 100 ) / ( 100 – loss )

CP= (18700*100)/(100-15)

CP= 22000

To get profit 1.5% S.P=?

S.P=[ 100 +Gain]/100 * C.P

S.P =[ 100+15]/100 * 22,000

S.P=25300

10 men can complete a job in 14 days How long will it take 4 men to finish the same job if they work at the same rate?

A) 33

B) 35

C) 37

D) 39

10 men can complete work in = 14 days
