From the given data,

P = 140

But it is given that,

40% of Q + Q = 140 = P

=> Q + [40Q/100] = 140

=> [100Q + 40Q]/100 = 140

=> 140Q = 140 x 100

=> Q = 100

Now,

 3/25 of Q 

= (3/25) x 100

= 3 x 4 

= 12 

Required 3/25 of Q  = 12.

Except mirage, all others are sources of water.

Let total amount = Rs. P

Total expenditure = (23 + 33 + 19 + 16)% of P = 91%ofP

Remaining money = (100 - 91)% of P = 9% of P

But given in the question that,

9% of P = 504

9p/100 = 504

=> P = 50400/9

=> P = Rs. 5600

Required money spent on Food & Insurance = 23 + 33 %

= 56% of 5600

= 56 x 5600/100 = 56 x 56 = Rs. 3136

Given in municipality election 54% votes have won by 1080

Let the total number of votes be x.

 54x100 - 46x100 = 1080

8x = 108000

x = 13,500

Therefore, total number of votes = 13,500.

The given series is 9 81 ? 6561 59049

It follows a pattern that

9

81 = 9 x 9

729 = 9 x 9 x 9

6561 = 9 x 9 x 9 x 9

59049 = 9 x 9 x 9 x 9 x 9

Hence, the missing number in the series is 729.

RAM is used as a short-term memory because of its volatility.

The Indian Space Research Organisation (ISRO) has successfully launched its 3136 kg GSAT-19 communication satellite with its brand new and heaviest – Geosynchronous Satellite Launch Vehicle Mark-III D-1 (GSLV-Mk III D-1) satellite into Geosynchronous Transfer Orbit (GTO) from the Satish Dhawan Space Centre (SDSC) in Sriharikota, Andhra Pradesh on June 5, 2017. The satellite GSAT-19 has an intended life span of 10 years and is developed to improve telecommunication and broadcasting areas. The GSLV-Mk III is popularly known as “fat boy” and is developed for 15 years at a cost of around Rs 300 crore. The rocket is capable of carrying payloads of up to 4,000 kg into the GTO and 10,000 kg into the Low Earth Orbit (LEO). The GSLV-Mk III is a three stage rocket. Its first stage is made of two strap on motors filled with solid fuel. The second stage uses the liquid fuel and the third is the cryogenic upper stage “C25”, which is powered by the highly complex indigenous cryogenic engine “CE20”. The number 20 denotes the 20-ton thrust it generates for the rocket to reach the intended height with the heavy mass on board.
