Question

plzz solve 1 and 2 number ​

Answer 1

Step-by-step explanation:

i)

Let the principal be Rs. P

R=4½% p.a. = 9/2% p.a.

T= 4 yrs 8 months= 4 yrs + 8/12 years = 4⅔ yrs= 14/3 yrs

S.I.= Rs. 21

Therefore,

(P×R×T)/100= 21

=> P×9×14/3×2×100=21

=> P= 21×100×2×3/ 9×14

=> P= 100

Therefore,

Principal = Rs. P = Rs. 100

ii)

Let the principal be Rs. P

R= 8% p.a.

T= 15 January to 22nd August= 219 days= 219/365 years = 3/5 years

S.I.= Rs. 62.40

Therefore,

P×R×T/100= 62.40

=> P×8×3/5×100= 62.40

=> P = 62.40×100×5/8×3

=> P = 1300

Therefore,

Principal= Rs. P= Rs. 1300
