the banker ' s gain of a certain sum due 3 years hence at 10 % per annum is rs . 36 . what is the present worth ?
a ) rs . 400 , b ) rs . 300 , c ) rs . 500 , d ) rs . 350 , e ) none of these
Choose the correct option letter a-e.
| solution banker ' s gain = txd / 100 = 36 therefore txd = 36 x 100 txd = 3600 therefore present worth = 3600 / 3 = rs . 1200 answer a
Final answer: a | explanation : let the present worth be rs . x . sum due in 3 years = ( x + 36 ) t = 3 years r = 10 % p . a . b . g . = s . i . on present worth for 3 years = ( x * 3 * 10 ) / 100 = 36 30 x = 3600 x = 120 answer : e

j is 25 % less than p , so j = 0.75 p j is 20 % less than t , so j = 0.80 t t = j / 0.80 = 0.875 p q = 1 - 0.875 = 0.125 = 12.5 % answer : e
Final answer: e

let's assume p = 100 j = 75 j = ... |
j is 25 % less than p and 20 % less than t . t is q % less than p . what is the value of q ?
a ) 93.5 , b ) 90 , c ) 6.75 , d ) 6.25 , e ) 2
Choose the correct option letter a-e.
| j = 0.75 p and j = 0.80 t , so 0.75 p = 0.80 t and t = 0.9375 p . so t is 6.25 % less than p . the answer is d .
Final answer: d | j = 75 / 100 p = 80 / 100 t t = 80 / 75 p = 16 / 15 p q = 100 - ( 100 * 15 / 16 ) = 6.25 % answer : d
