Dear sir

Please explain the logic of question 7

P[1 +(r/100)]^2 / P[1 + (r/100)]^1 = 4/5

1 + (r/100) = 4/5

r/100 = 1/4

r=25%

6th me 24 kse aya

i’m also thinking the same

2304………… 2500

1156…………1250

576…………625

24…………..25

diff.

25-24=1

Therefore,

(1/24)*100= 25/6= 4.16%.

when we’re taking ratio to fir square kaise le lia,? ye logic samjh nahi hai, mtlab

jab hm log ratio niklte to both side ko same value de divide karte h na ki square lenege

576:625 ye value same digit se divide nhi hogi

Yes

But shortcut is being used here, we can do like this

Shortcut::

2304 == 2500

576 == 625

Take square roots

24 == 25

diff. = 1

= (1/24) * 100 = 4.16%

2304………… 2500

1156…………1250

576…………625

24…………..25

diff.

25-24=1

Therefore,

(1/24)*100= 25/6= 4.16%

Got it thanks

..

2304………… 2500

48 (root) 50 (root)

2/48=4.16

1st mein 6472.22 kaise aa rha?

pura solve kariye khud se

x(18/100)*2 – 6000*(14/100)*2 = 650

0.36x – 1680 = 650

0.36x= 2330

x = 2330/0.36

x= 6472.22

thanks, got it, galti kr rha tha main

Isn’t it compounded??? But in question it’s si

yes take SI

SI and CI for 1st year are same na

so u can take any, it wont affect answer

Logic is simple first year simple and compound interest are equal.and second if rate is equal we earn money more than on the first years simple interest.

ty

9/10

please explain no. 8.. my answer comes 616.

Amount paid at the end of 2 year = (800*10*2)/100 + 800 = 960

Amount left as principal for the second year = 560

Amount to be paid after 2nd year = (560*10)/100 +560 = Rs.616

will count for 1 year = (800*10*1)/100+800 = 880

why 1 year?? we are to find out Amount paid at the end of 2 year, right?

400 Rs is paid after a year

so 1st we will find for 1 year which is 880 the

880-400 = 480 is principal for 2nd year

thank u.

Thanks Banya Ma’am :))
