A+B+C=3x65=195 ---(i)
A+B+C+D=4x70=280 ---(ii)
Eqn (ii) - (i), D=85
Also, B+C+D=3x75=225 => B+C=140 ---(iii)
Eqn (i) - (iii), A=55
Therefore, weight of A=55 Kg.

A person sold an article for 1840 Rs. And profit incurred will be 12.5% more than the loss incurred when article is sold for 1500 rs. At what price it should be sell to get 20% profit?

Devendra Marghade 1 Month ago

Ans: Rs. 1992

Let CP=Rs. x, then Profit when SP is 1840 = (112.5/100)*Loss when SP is 1500
(1840-x) = (112.5/100)*(x-1500)
184000 - 100x = 112.5x - 168750
Solving, we get x = 1660
So, SP when profit is 20% = 1660*(120/100) = 1992 Rs.

There is a splendid fountain in the heart of Paris Tourists throw coins into the fountain in the belief that their wishes would come true. At the end of each day, a group of urchins jump into the water and pick up the coins. It is a tradition that they share the amount equally On Friday, had 5 urchins not shown up due to rain, each of those present would have received a Euro more But had it been a sunny day and there had been 15 more urchins, each would have received 2 Euros less, Find the total number of Euros in the fountain on Friday

Let x urchins gets y Euros each, when all urchins are present, then total Euros=x*y
As per given conditions, (x-5)*(y+1)=xy ⇒ x-5y=5 ---(i) and
(x+15)*(y-2)=xy ⇒ -2x+15y=30 ---(ii)
Solving above equations, we get x=45, y=8
Therefore, total number of Euros=45*8=360

If the sum of the first 43 terms of an arithmetic progression is 2967, then find the sum of the 11th and the 33rd terms of the same series.

G.S.Kantharao 4 Months ago

S43=43(2a+42d)/2[through formulaSn=n{2a+(n-1)d}/2]
So S43=43(2a+42d)/2=2967
Now T11=a+10d
T33=a+32d
T11+T33=2a+42d=2967*2/43
=138

Devendra Marghade 4 Months ago

Ans: 138

For A.P. series, here n=43, S=2967. If First term=a, Difference=d, then sum of an A.P. series S=(n/2)[2a + (n-1)d]
2967 = (43/2)(2a + 42d)
69 = a + 21d ---- (i)
Sum of 11th term and 33rd term = (a + 10d) + (a + 32d) = 2a + 42d = 2 x (a + 21d) = 2 x 69 = 138

bank advertises that you can double the money if you invest it with them for 8 years, what is the rate of Interest offered by them?

Reply Like? Yes | No

Devendra Marghade 4 Months ago

Money doubles in 8 years => Interest earned is equal to principal
Let Principal=P, Rate=R %, then P*R*8/100 = P
R = 100/8 = 12.5%

8*R**P/100=P
R=100/8=12.5%

their sides. The first person wins if the same color appears on both the dies and the second

red sides and 1 blue side, find the color(s) on the second one.
