In a pet shop, there are 120 eyes and 172 legs. How many birds and pup...
Let's solve the problem by setting up a system of equations based on the given information.


Let's assume the number of birds as 'b' and the number of puppies as 'p'.


Each bird has 2 eyes and 2 legs, and each puppy has 2 eyes and 4 legs.


From the information given, we can create the following equations:


2b + 2p = 120 (equation for the total number of eyes) 2b + 4p = 172 (equation for the total number of legs)


Simplifying these equations, we have:


b + p = 60 b + 2p = 86


By subtracting the first equation from the second equation, we can eliminate 'b':


(b + 2p) - (b + p) = 86 - 60 p = 26


Substituting the value of 'p' back into the first equation:


b + 26 = 60 b = 34


Therefore, the number of birds is 34 and the number of puppies is 26.


Hence, option 1 is the correct answer: Birds = 34 and Puppies = 26.

Say x is the number of puppies and y is the number of birds. As all total we have 172 legs then 4x+2y=172 and for 120 eyes we have 2x+2y=120.
Solve it and you will get 2x=52 ie. x=26 ie. 26 puppies and t=34. So option A is correct.

120 eyes means 60 all total birds & puppies. Here we can see only option (a) has total 34+26=60 total birds & puppies so the answer is a).

Similar Quant Doubts

For a period of more than two centuries paleontologists have been intrigued by the fossilized remains of pterosaurs, the first flying vertebrates. The issues, which puzzle them, are how these heavy creatures, having a wingspan of about 8-12 meters managed the various problems associated with powered flight and whether these creatures were reptiles or birds. Perhaps the least controversial assertion about the pterosaurs is that they were reptiles. Their skulls, pelvises, and hind feet are reptilian. The anatomy of their wings suggests that they did not evolve into the class of birds. In pterosaurs a greatly elongated fourth finger of each forelimb supported a wing like membrane.The other fingers were short and reptilian, with sharp claws. In birds the second finger is the principal strut of the wing, which consists primarily of feathers. If the pterosaurs walked on all fours, the three short fingers may have been employed for grasping. When a pterosaurs walked or remained stationary, the fourth finger, and with it the wing, could only urn upward in an extended inverted V- shape along each side of the animals body. In resemblance they were extremely similar to both birds and bats, with regard to their overall body structure and proportion. This is hardly surprising as the design of any flying vertebrate is subject to aerodynamic constraints. Both the pterosaurs and the birds have hollow bones, a feature that represents a savings in weight.There is a difference, which is that the bones of the birds are more massively reinforced by internal struts. Although scales typically cover reptiles, the pterosaurs probably had hairy coats. T.H. Huxley reasoned that flying vertebrates must have been warm-blooded because flying implies a high rate of metabolism, which in turn implies a high internal temperature. Huxley speculated that a coat of hair would insulate against loss of body heat and might streamline the body to reduce drag in flight. The recent discovery of a pterosaur specimen covered in long, dense, and relatively thick hair like fossil material was the first clear evidence that his reasoning was correct.Some paleontologists are of the opinion that the pterosaurs jumped from s dropped from trees or perhaps rose into the light winds from the crests of waves in order to become airborne. Each theory has its associated difficulties. The first makes a wrong assumption that the pterosaurs hind feet resembled a bats and could serve as hooks by which the animal could hang in preparation for flight. The second hypothesis seems unlikely because large pterosaurs could not have landed in trees without damaging their wings. The third calls for high aces to channel updrafts. The pterosaurs would have been unable to control their flight once airborne as the wind from which such waves arose would have been too strong.Q.According to the passage, some scientists believe that pterosaurs
