If tanvi gives an interest of rs40 for one years at 5rate p.a.what is the sum she has borrowed​

Answer» N ;

SI = 40

Time = 1 year

Rate = 5%

Principal = (?)

SI = P × R × T / 100

40 = P × 5 × 1 / 100

P = 40 × 100 / 5 × 1

P = 4000 / 5

Principal = 800

Hence, 800 is the sum she has borrowed .

Hope it HELPS !!
