Given :- A sum of Rs 1700 was lent partly at 4% p.a. on simple interest and partly at 6%. The total interest received after 3 year was Rs 252. The ration of the money lent at 4% to that lent at 6% is.
Answer :-
Let Rs. x was given at 4% p.a and rest Rs.(1700 - x) given at 6% p.a .
since,
→ SI = (P * R * T)/100 .
so,
→ (x * 4 * 3)/100 + [(1700 - x) * 6 * 3]/100 = 252
→ 12x + 18(1700 - x) = 25200
→ 12x + 30600 - 18x = 25200
→ 30600 - 25200 = 6x
→ 5400 = 6x
→ x = Rs.900 .
therefore, Rs.900 lent at 4% and Rs.800 lent at 6% .

Answer:
The ratio of the money lent at 4% to that lent at 6% is 9:8.
Step-by-step explanation:
Given: Rs 1700 was lent partly at 4% p.a. on simple interest and partly at 6% & interest received after 3 years was Rs 252.
To find: ratio of the money lent at 4% to that lent at 6%.
Let amount lent at 4% p.a be x and at 6% p.a be Rs.(1700 - x).
we know that S.I = (P * R * T)/100 .
→ (x * 4 * 3)/100 + [(1700 - x) * 6 * 3]/100 = 252
→ 12x + 18(1700 - x) = 25200
→ 12x + 30600 - 18x = 25200
→ 30600 - 25200 = 6x
→ 5400 = 6x
→ x = Rs.900 .
So, 1700-x=1700-900
=800 Rs
Therefore, amount lent at 4% is Rs.900 and at 6% is Rs.800.
Hence ratio of the money lent at 4% to that lent at 6% = 900/800
=9:8
