Murali travelled from city A to city B at a speed of 4 kmph and from city B to city C at 6 kmph. What is the average speed of Murali from A to C given that the ratio of distances between A to B and B to C is 2 : 3?
A. 48 kmph | [
"5",
"7",
"33",
"28"
] | A | Let the distances between city A to B and B to C be 2x km and 3x km respectively.
Total time taken to cover from A to C
= (2x)/4 + (3x)/6 = (6x + 6x)/12 = 12x/12 = x Average speed = (2x + 3x)/(x) = 5 kmph.

"2240",
"2200",
"None of these",

Let P.W. be Rs.x.
Then, S.I. on Rs. x at 16% for 9 months = Rs. 240.
x × 16 × (9/12) × (1/100) = 240 or x = 2000.
P.W. = Rs. 2000.
Sum due = P.W. + T.D. = Rs.(2000

Based on this year's costs, an orcharde grower budgets P dollars for planing N new trees next year. If the average cost of planting each tree were to increase 10% from this year's cost, then the greatest number of trees that the orchard grower could plant next year using P dollars would be | [
"25% less than N",
"20% greater than N",
"9% less than N",
"equal to N"
] | C | Correct answer is (A).
This year, the price of a tree is price1=P/N.
If this price increases by 10% it becomes price2=P/N*1.10
Then with P dollars, you can grow P/price2 tress i.e. P/(P/N*1.10) i.e. N/1.1 i.e. .91% | AquaRat_train |
