"45 m",
"60 m",
"67 m",

2x + 20 = 100
2x = 80
x = 40.
Hence, length = x + 20 = 60 m

] | D | Explanation:
60% of X + 2/3 of 39 = 44

A sum was put at simple interest at a certain rate for 10 years . Had it been put at 5% higher rate , it would have fetched Rs.400 more. What was the Sum? | [
"s.1400",
"s.800",
"s.1200",
"s.1000"
] | B | At 5% more rate, the increase in S.I for 10 years = Rs.400 (given)
So, at 5% more rate, the increase in SI for 1 year = 400/10 = Rs.40/-
i.e. Rs.40 is 5% of the invested sum
So, 1% of the invested sum = 40/5
Therefore, the invested sum = 40 × 100/5 = Rs.800 Answer: B | AquaRat_train |
