% per annum, interest payable
quarterly ?​

Answer 1

Answer:

CI IS ₹162.50

Step-by-step explanation:

PARAMETERS GIVEN,

PRINCIPAL = ₹2560

TIME = 1/2 yr

RATE% = 12 1/2%

            = 25/2%

SO,

A.T.Q.,

A = P(1+R/400)⁴ⁿ

   = 2560[1+ 25/(2*400)]⁴*¹/₂

   = 2560[33/32]²

   = (2560*33*33)/(32*32)

   = ₹2722.50

SO,

CI = A-P

   = ₹2722.50-₹2560

   = ₹162.50

SO,

CI IS ₹162.50

Answer 2

Step-by-step explanation:

principal =orginal principal

time=1/2×4=2

rate=25/2×4 = 50 %

first half = p( 1+r/100) ×n

= 2560( 1+50/ 100) ×1

= 2650(100+50/100) ×1

= 2650(150/100) ×1

=2650(30/20) ×1

=2650( 6/4) ×1

=2650(3/2) ×1

2650×3/2

3975

second half =p(1+r/100) ×n

3975 ( 1+ 50/ 100) ×1

3975× 150/100 ×1

3975× 30/ 20×1

3975×6/4×1

3975× 3/2 ×1= 5962.5
