One pipe can fill a tank three times as fast as another pipe. If together the two pipes can fill tank in 36 min, then the slower pipe alone will be able to fill the tank in ?

Total events = n (s) = 2⁵ = 32
n(E) of getting heads = 1
p(E) = 1/32
? n(E) = 1 - p(E) = 1 - 1/32 = 31/32

Number of trees that can be planted on one side of road = (1760 / 20) + 1
= 88 + 1
=89

? Trees on the both side = 2 x 89=178

1307 x 1307 = (1307)²
= (1300 + 7 )²
= (1300)² + (7)² + 2 x 1300 x 7
= 1690000 + 49 +18200
= 1708249

? 2?R - 2?r = (176-132)
? 2?(R-r) = 44
? R-r = ( 44 x 7 )/ (2 x 22)
= 7 m

Given Exp. = (1/2 x 1/4 + 20) / (2 + 20) = (161/8) x (1/22)
= 161 / 176

NA

If the required fraction be P
According to the question
(P x P) / (1/P) = 18²⁶/₂₇
? P³ = 512/27
? P = 8/3 = 2²/₃

(0.04)³ = 0.04 x 0.04 x 0.04
= 0.000064

We have p³ + q³ + r³ ? 3pqr = (p + q + r) (p² + q² + r² ?pq ? qr - rp)
Here p = a ? 4, q = b ? 3, r = c ?1
So, given expression is (p + q + r) (p² + q² + r² ? pq ? qr ? rp)
= (a ? 4 + b ? 3 + c ? 1) (p² + q² + r² ? pq ? qr ? rp)
= (a + b + c ? 8) (p² + q² + r² ? pq ? qr ? rp)
= (8 ? 8) (p² + q² + r² ? pq ? qr ? rp)
? (a ? 4)³ + (b ? 3)³ + (c ? 1)³ ? 3 (a ? 4) (b ? 3) (c ? 1) = 0

Let 3571 + x - 6086 = 115
Then, x = 6086 +115 -3571
= 6201-3571
= 2630
