Let the ratio is x:y
(2x+4y):(x+y)=3:1
2x+4y=3x+3y=>x=y
Now x:y=1:1

How many Kg ot wheat @ Rs. 14 per kg should be mixed with 32 kg of wheat @ Rs
22 per kg so that there is a profit of 25% by selling the mixture @ Rs 23.90 per kg

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
14x + 704 = 19.12x + 611.84
5.12x = 92.16
x = 18

Gold is 19 times as heavy as water and copper is 9 times as heavy as water. In
what ratio should these be mixed to get an alloy 15 times as heavy as water.

Required ratio = (15-9)/(19-15) = 6/4 = 3/2
Therefore, these should be mixed in the ratio 3:2.

Does anyone think that the prize system of today's puzzle needs to be changed and it needs to return the earlier system of distribution of prize amount. Whoever wants to win the prize needs to compete with other candidates. Otherwise there is no benefit of becoming topper of the week again if you already won a prize in a month.

6*6=36
If we assume the number is 37 then
37-1=36 divisible by 6
And 37-2=35 divisible by 7

Devendra Marghade 6 Months ago

Let the number of students be 'x' then x-1=6y and x-2=7z
=> 6y+1 = 7z+2 or 6y - 7z = 1
Which is true for y=6, z=5
So, minimum number of students=6y+1 or 7z+2 = 37

Calculate the l. C. M
That is 30 , 30+4=34 when divisible by 3 gives one remainder but does got go with 2,5 . So the next number can be 37. It helds all the option

Please help with this problem.
If two numbers are divided by a dividor produce remaindes 3 and 4, but then the sum of the numbers is divided by that divisor gives remainder 2. Find the divisor.

Reply Like? Yes (1) | No

Devendra Marghade 7 Months ago

Ans=5

Let the divisor be a, first no. be x and second no. be y, then in given 3 conditions
X = ak + 3 —(i)
y = al + 4 —(ii)
x+y = am + 2 —(iii)
Adding (i) & (iii), and Substituting x+y in (iii), we get (ak+3) + (al+4) = am+2
a(m-k-l) = 5
Prime factorization gives a=5 or 1
As divisor cannot be 1 in above given conditions, so divisor a=5.
