ANSWERS SOLUTIONS:
1- (c)
size of each cask must be equal to greatest capcity .Hence ,capacity of cask must be equal to the HCF of 403, 434 and 465.
capacity of a cask = required HCF i.e.31
Required no of cask = 403/31 + 434/31 + 465/31
= 13 + 14 + 15 = 42
2- (b)
Let the number be 29x and 29y respectively
where x and y are prime to each other.
so LCM of 29x and 29y = 29xy
Now,29xy = 4147
so xy = 143 = 11*13
so Numbers are
29*11 = 319 and 29*13 = 377
so Required sum = 377+319 = 696
3- (b)
Let the number be = x
so x/5 + 4 = x/4 - 10
x/4 - x/5 = 10 + 4
(5x-4x)/20 = 14
x = 20*14 = 280
4- (b)
5- (c)
W1/M1D1 = W2/M2D2
1/(8*12) = 1/2/(12*D2)
D2 = 4 days
6- (b)
Acc to ques.
(M+A+S)/3 = 11111
M+A+S = 33333
M - 11111 = 11111-S
M+S = 22222
so value of property of Ambani
= 33333-22222= 11111
7- (c)
8- (a)
9- (b)
10- (c)
