Ranjan Singh makes statues of brass. Brass is an alloy of copper and zinc. Ranjan uses two varieties of brass for different kinds of statues. Variety 1 contains copper and zinc mixed in the ratio $7: 4$ and variety 2 contains these metals in the ratio $5: 3$. Ranjan makes an elephant statue from variety 1 and a horse statue from variety 2. The elephant statue weighs 176 g and it is known that the brass used in the horse statue contains 135 g zinc.
Q.1. Find the quantity of copper present in the brass used to make the elephant statue.

Q.2. How much copper is contained in the brass used to make the horse statue?
(a) 165 g $\quad$$\quad$(b) 175 g$\quad$$\quad$ (c) 205 g$\quad$$\quad$ (d) 225 g
Q.3. How much zinc is contained in the brass used to make the two statues?
(a) 169 g $\quad$$\quad$(b) 179 g$\quad$$\quad$ (c) 189 g$\quad$$\quad$ (d) 199 g
Q.4. The ratio of the quantities of copper and zinc used to make the two statues is:
(a) $113: 98$ $\quad$$\quad$(b) $337: 148$ $\quad$$\quad$(c) $221: 199$ $\quad$$\quad$(d) $337: 199$
