If x + y = 6 and 3x - y = 4, then x - y is equal to
x + y = 6
⇒ y = 6 - x
Now, 3x - y = 4
or 3x - (6 - x) = 4
or 3x - 6 + x = 4
or 4x = 10
or x = 5 2
∴ y = 6 - 5/ 2 = 7 2
∴ x - y = 5/ 2 - 7 2 = -1
If 2 tables and 3 chairs cost Rs 2,315 and 2 chairs and 3 tables cost Rs 2,910,what is the cost of 4 chairs?
Let the cost of one table and chair be Rs x and Rs y
2x + 3y = 2315 .....(i)
3x + 2y = 2910 .....(ii)
Solving (i) and (ii) we get
y = 225, x = 820
∴ The cost of 4 chairs is Rs (4 x 225)
= Rs 900.00

The interior angles of a pentagon are in the ratio 1 : 2 : 3 : 5 : 9. The largest angle of the polygon is
Let angle be x
So, 1st angle is 1x
2nd angle is 2x
3rs angle is 3x
4th angle is 5x
& 5th angle is 9x
Sum of these angles is (1 + 2 + 3 + 5 + 9)x = 20x
Sum of the interior angle of a pentagon is = 540º
Hence x = 540 /20 = 27º
So, largest angle is 27 x 9 = 243º

By selling 12 marbles for a rupee, a shopkeeper loses 20%. In order to gain 20% in the transaction, he should sell the marbles at the rate of how many marbles for a rupee?
Given : S.P. of 12 marbles / 0.8 = Rs. 1.25
Now S.P. of 12 marbles at a gain of 20%
= C.P. x 1.2 = 1.25 x 1.2 = Rs. 1.5
It means in order to gain 20% he should sell 12 marbles for Rs. 1.5. Or for Re . 1 he should sell 12 /1.5 = 8 marbles.

Let PQ = 64 km A man starts from P and walks 32 km on first day, on second day he walks only 16 km, on third day he walks 8 km, on fourth day he walks just half, i.e. 4 km. He will reach Q in
Distance between PQ = 64 km
Distance covered on the 1st day = 64 2 = 32 km
Distance covered on the 2nd day = 32 2 = 16 km
Like wise Total distance covered = 32 + 16 + 8 + 4 + ..........
This is an infinite geometric series whose first term is 32 and common ratio = 1 2

A can do a certain work in the same time in which B and C together can do it. If A and B together could do it in 10 days and C alone in 50 days, then B alone could do it in :
A = B + C
⇒ A + B + C = 6 units
But A = B + C
⇒ 2(B + C) = 6 units
⇒ B + C = 3 units
⇒ B + C - C = 3 - 1 = 2 units
⇒ B = 2 units
Hence, B alone did it in:
50 2 = 25 days
