Ten years ago,the average of family of four members was 24 years.Three children having been born,the average age of family is same today.What are the present ages of children if two children are identically twins and differ by two years from the younger one?

Reply Like? Yes | No

(6 Days ago)

24×4 =96 + 4×10 = 136
current age = 24×7 = 168
hence children age = 32
2A + A - 2 = 32
A = 34/3 = 11.33 not possible
data is wrong as child can not be older than 10 years

Let q are the no of people
150=aq+r----(1)
270=bq+r----(2)

Eqn. 2 -1=q(b-a)=120

Eqn.3-1=q(c-a)=170

Additionally,
Picking from second variety can be done in 6 ways including picking zero {0,1,2,3,4,5,6}

Two articles A and B, with the same marked price were sold at 15% and 12% discounts respectively. Percentage of the profit earned on articles A and B was 6.25% and 20% respectively. The cost price of article B was Rs.160 less than the cost price of article A. Find the marked price of the each article.

Reply Like? Yes | No

(3 Months ago)

Let the CP of A=x+160 and B=x. Marked Price of A and B=P.
Then, SP of A = P*85/100 = (106.25/100)* (x+160) ---> 17P = (x+160)*21.25 ---(i)
SP of B = P*88/100 = (120/100)*x ---> 11P = 15x ---(ii)
Solving (i) & (ii), we get Marked Price = P=2400 and CP of B=x=1760, CP of A=(x+160)=1920

a)40 and 120
b)80 and 180
c)180 and 320
d)210 and 300
e)300 and 350
This question is from this site and I've also placed my reasoning/solution for it.
Any help will be most appreciated.

It is 210 and 300
Total candies 500
Out of these candies with both maximum is 300. Since chocklet chips is subset to sprinkles.
60 is neither of them. So either of them are 500-60=440
Now minimum =350+300-440=210
So it will be 210 and 300

Reply Like? Yes | No

Ans: 18 kg

Let x kg of wheat costing Rs. 14/kg is mixed, then (x*14 + 32*22)/(x+32) = 23.9*(100/125)
(14x + 704) / (x+32) = 19.12
