Q:

The true discount on a bill due 9 months hence at 12% per annum is Rs 540. Find the amount of the bill and its present worth?

A) 1600 B) 7000
C) 6000 D) 6500
 
Answer & Explanation Answer: C) 6000

Explanation:

Let amount be Rs.x then,  

 [X * R * T] / [100 + (R * T)] = T.D  

=> [x * 12 * (3/4)] / [100+(12 * 3/4)] =540  

=> x = 6540  

Amount = Rs.6540   

P.W = Rs.(6540 -540) = Rs.6000

In a 100 m race, A can give B 10 m and C 28 m. In the same race B can give C:

A) 18 m B) 20 m
C) 27m D) 9 m
 
Answer & Explanation Answer: B) 20 m

Explanation:

A : B = 100 : 90.

 

A : C = 100 : 72.

 

B:C = B/A*A/C = 90/100*100/72 = 90/72

 

When B runs 90 m, C runs 72 m.

 

When B runs 100 m, C runs (72/90*100)m = 80m

 

 B can give C 20 m.
