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.
(a) 98 g $\quad$$\quad$(b) 112 g$\quad$$\quad$ (c) 121 g $\quad$$\quad$(d) 132 g
Q.2. How much copper is contained in the brass used to make the horse statue?
(a) 165 g $\quad$$\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) $337: 199$
