the rate of interest being 5% per annum at simple
interest. The first part is​

Answer 1

Answer:

Let the three parts be x,y and z. 

Then, x+ 100x×2×5=y+100y×3×5=z+100z×4×5

⇒x+10x=y+203y=z+5z

1011x=2023y=56z=k(say)

∴x=1110k,y=2320k,z=65k

Given, x+y+z=2379

⇒1110k+2320k+65k=2379

⇒15181380k+1320k+1265k=2379

⇒3965k=2379×1518

⇒k=39652379×1518

⇒ First part = Rs. 11×510×3×1518= Rs. 828
