Question

Yadi kisi dhan ka mishra dhan 4 varsho me 460 rupee aur 5 varsho me 500rupee ho to bayan dar kya hogi

Answer 1

Answer:

460 = P + Prt/100 = P(1+r4/100) = P(100+4r)/100

500 = P(100 + 5r)/100

take ratio

500/460 = (100+5r)/(100+4r)

(100 + 5r)×460 = (100+4r)×500

(100 + 5r)×46 = (100+4r)×50

5×46r +4600 = 4×50r +5000

230r - 200r = 5000 - 4600

30r = 400

r = 400/30 = 40/3 = 13 1/3%
