Aspects = 4 x 5 x 2

TSA = 2 (4 x 5 + 5 x 2 + 4 x 2) = 2(20+10+8)=2x38 = 76 sq m

So blocks required = 76 x 17 = 1292

For 5 rooms 1292 x5 = 6460

Q21. One Grand Father Has 3 Grand Children Two Of The Age Difference Is 3.eldest Child Age Is 3 Times The Youngest Childs Age And The Eldest Child Age Is Two Year More Than The Sum Of Other Two Children. F

Let the period of oldest kid is E , that of senior kid is M and that of most youthful youngster is Y, then, at that point, as per the given circumstances

E = 3Y (1) and E = 2 + M + Y (2)

Third condition is fairly muddled, as per this condition two of the age distinction is 3 so three cases will emerge

1) E - M = 3, ......(3)

2) M - Y = 3, ......(4)

3) E - Y = 3, ......(5)

on the off chance that we take first of the 3 circumstances, on settling (1), (2) and (3) we will get E = 3, M = 0, Y = 1 which is off-base currently on addressing (1), (2) and (4) we will get E = 15, M = 8, Y = 5

similitude on tackling (1), (2) and (5) we will get E = 4.5, M = 1, Y = 1.5

just E = 15, M = 8, Y = 5 is right so time of senior youngster is 8 years.
