Question

Felicity, Rainbow, Prudence and Bob, the unicorn friends, are prancing around in the forest. They notice seven bees and five cockroaches, and in the trees they spot eight spiders. There are also three deer and four boars. Behind a bush, they can see a pair of antlers. How many legs do all the numbered beasts combined amount to?
A:188
B:184
C:170
D:162

Answer 1

Answer: B:  184

Step-by-step explanation:

Felicity, Rainbow, Prudence and Bob, the unicorn friends, are prancing around in the forest.

No. of unicorns = 4

Each unicorn has 4 legs.

Total legs in 4 unicorns = $4\times4=16$   (1)

No. of bees = 7

Also, a bee has 6 legs, then the total legs of 7 bees = $7\times6=42$  (2)

No. of cockroaches= 5

Each cockroach has 6 legs , so total legs of cockroaches =$5\times6=30$   (3)

No . of spiders = 8

Each spider has eight legs , the total number of legs of 8 spiders = $8\times8=64$       (4)

There are also three deer and four boars. Behind a bush, they can see a pair of antlers i.e. one more deer is behind the bushes .

Since each deer and boar has 4 legs , so total legs of 4 deer and 4 boars=

$4(4+4)=4(8)=32$        (5)

Now , Add (1), (2) , (3), (4) and (5) , we get

The total number of legs all the numbered beasts combined amount to =

$16+42+30+64+32=184$

∴ The total number of legs of all those beasts = 184

Option (B) is correct.

Answer 2

Answer: OPTION B

Step-by-step explanation:

There are seven bees. Each bee has 6 legs. Then:

$legs_{(bees)}=7*6=42$

There are five cockroaches and each has 6 legs. So:

 $legs_{(cockroaches)}=5*6=30$

Since there are eight spiders and we know that each has 8 legs:

 $legs_{(spiders)}=8*8=64$

There are three deers, but the exercise says that there are  a pair of antlers begind a bush and this is a characteristic ruminant mammals. Since deers are ruminant mammals, we can say that there are 4 deers.

A deer has 4 legs. Then:

$legs_{(deers)}=4*4=16$

Since there are four boars and each has 4 legs, we know that:

$legs_{(boars)}=4*4=16$

We know that a unicorn has 4 legs, and Felicity, Rainbow, Prudence and Bob are unicorns, then:

$legs_{(unicorns)}=4*4=16$

Therefore, the total amount of legs of all those beasts is:

$total\ legs=42+30+64+16+16+16=184$
